ELF/LD: Avoid producing hidden and internal dynamic symbols
Always turn hidden and internal symbols which have a dynamic index into
local ones. This is required by the the ELF gABI[1]:
"A hidden symbol contained in a relocatable object must be either
removed or converted to STB_LOCAL binding by the link-editor when the
relocatable object is included in an executable file or shared object."
"An internal symbol contained in a relocatable object must be either
removed or converted to STB_LOCAL binding by the link-editor when the
relocatable object is included in an executable file or shared object."
The ELF linker usually respects this requirement, however in the case
where a dynamic symbol has been preallocated due to a reference of the
default export class aka visibility from the object being linked, and
then merged with a hidden or internal symbol definition from within the
same object, then the original export class is carried over to the
output dynamic symbol table, because while merging the generic ELF
linker only converts affected dynamic symbols to local when they are
defined or referenced by the object being linked and a dynamic object
involved in the link both at a time.
The dynamic symbol produced confuses then the dynamic loader at the run
time -- the hidden or internal export class is ignored and the symbol
follows preemption rules as with the default export class.
In the MIPS target it happens when `mips_elf_record_global_got_symbol'
creates a dynamic symbol when a call relocation is encountered.
Additionally if the undefined symbol referred by such a relocation does
specify the intended export class, then a local dynamic symbol is
created instead, which is harmless and allowed, but useless. Normally
no local dynamic symbols are created, except for a single dummy one at
the beginning.
Correct the problem by removing the extra check for a dynamic symbol
being defined or referenced by the object being linked and a dynamic
object involved in the link both at a time. The test cases included
cover the internal and hidden symbol cases, as well as a protected
symbol for a reference, the handling of which is unchanged by this fix.
Both cases described above are covered, that is where an internal or
hidden dynamic symbol is produced and where a local one is.
NB this change affects CRIS results where some symbols in the static
table produced in a final link are now converted from STV_HIDDEN to
STB_LOCAL. This happens whenever the `elf_backend_hide_symbol' handler
is called, so the affected symbols must have been chosen for entering
into the dynamic symbol table, except in these test cases no such symbol
table is produced. In fully linked binaries the static symbol table is
only used for debugging though, so such a change is fine.

arc: Remove EF_ARC_CPU_GENERIC constant.
The constant EF_ARC_CPU_GENERIC is defined in the include/elf/arc.h
file, and is used in a few places in binutils, however, this constant
should never make it into the elf header flags; we always set a valid
cpu type in the assembler, which should then be copied over during
linking.
There are some non-gnu arc compilers that don't write an architecture
type into the e_flags field, instead leaving the field as 0, which is
the EF_ARC_CPU_GENERIC value. This non-gnu compiler uses the machine
type to distinguish between the old and newer arc architectures, setting
the machine type to EM_ARC_COMPACT for old arc600, arc601, and arc700
architectures, while using EM_ARC_COMPACT2 for newer arcem and archs
architectures.
Previously when displaying the machine flags for an older EM_ARC_COMPACT
machine, if the e_flags had not been filled in, then we relied on the
default case statement to display the message "Generic ARCompact", while
in the EM_ARC_COMPACT2 case we specifically handled EF_ARC_CPU_GENERIC
to print "ARC Generic", leaving the default case to print a message
about unrecognised cpu flag.
After this commit EF_ARC_CPU_GENERIC has been removed, for both machine
types EM_ARC_COMPACT and EM_ARC_COMPACT2 we now rely on the default case
statement to handle the situation where the e_flags has not been filled
in. The message displayed is now "Unknown ARCompact" (for older arc
architectures) and "Unknown ARC" (for the newer architectures). The
switch from "Generic" to "Unknown" in the message string is for clarity,
calling the file "Generic" can give the impression that the file is
compiled for a common sub-set of the architectures, and would therefore
run on any type of machine (or at least any type of new or old machine
depending on if the machine type is ARC or ARCv2). However, this was
not what "Generic" meant, it really meant "Unknown", so that's what we
now say.
As part of the merging of the readelf flag reading code, I have unified
the strings used in displaying the ELF ABI. This means that for older
arc machines (arc600, arc601, and arc700) the string used for the
original ABI, and ABIv2 have changed, the current ABIv3 remains the
same. For the newer architectures (arcem and archs) the abi strings
remain unchanged in all cases.

Fix v850 bfd arch info printable names
Currently, it's not possible to manually set some of the v850 archs in
gdb:
(gdb) set architecture v850<TAB>
v850 (using old gcc ABI)
v850-rh850
v850e
v850e (using old gcc ABI)
v850e1
[...]
(gdb) set architecture v850 (using old gcc ABI)
Ambiguous item "v850 (using old gcc ABI)".
The problem is that "set architecture" is a GDB "enum command", and
GDB only considers an enum value to be the string up until the first
space. So writing "v850 (using old gcc ABI)" is the same as writing
"v850", and then that's not an unambiguous arch printable name prefix.
v850 is actually the only arch that has spaces in its printable name.
One can conveniently see that with e.g.:
(gdb) set max-completions unlimited
(gdb) complete set architecture
...
Rather than hack GDB into accepting this somehow, make v850 arch
printable names more like the printable names of the other archs, and
put the abi variant in the "machine" part, after a ':'.
We now get:
(gdb) set architecture v850<TAB>
v850:old-gcc-abi
v850:rh850
v850e
v850e1
v850e1:old-gcc-abi
v850e2
v850e2:old-gcc-abi
[...]
And now "set architecture v850:old-gcc-abi" works as expected.
I ran the binutils/gas/ld testsuites, and found no regressions. I
don't have a cross compiler handy, but I ran the gdb tests anyway,
which covers at least some snoke testing.
I think that the OUTPUT_ARCH in ld/scripttempl/v850.sc may have got
broken with the previous 2012 change, since I hacked v850_rh850.sc to
output "v850" and ld failed to grok it. I think it only works if the
old GCC ABI is the configured v850 default ABI. That's now fixed by
changing to use explicit v850:old-gcc-abi.
Also, this actually "fixes" an existing GDB test, which isn't likewise
expecting spaces in arch names, when GDB is configured for
--target=v850:
(gdb) FAIL: gdb.xml/tdesc-arch.exp: read valid architectures
bfd/ChangeLog:

Fix BFD format matching for x86_64-w64-mingw32 -m32 LTO.
In <https://sourceware.org/ml/binutils/2015-12/msg00190.html> (commit
4a07dc81356ed8728e204e9aabeb256703c59aef), Kwok fixed a problem with
the template used for a dummy BFD for an IR file for LTO on MinGW,
where the input and output formats are not the same.
A problem, however, remains in the case of linking for
x86_64-w64-mingw32 -m32, where LTO linking reports an ambiguity
between the pe-i386 and pei-i386 formats. An object (pe-i386) with
plugin data is being tested by the linker to see what formats match.
The default format initially set by the linker when
bfd_check_format_matches is called is pei-i386 (as that's the output
format from the linker script), which does not match, so the function
goes on to the loop over possible BFD vectors. The pe-i386 vector
matches, as it should. One other vector matches: the plugin vector.
bfd_check_format_matches tests a vector for matching by temporarily
modifying the BFD object to use that vector then using
_bfd_check_format on it. So the BFD object is temporarily using
plugin_vec. _bfd_check_format ends up using bfd_plugin_object_p which
uses plugin_object_p from ld which uses plugin_get_ir_dummy_bfd which
succeeds, having created a BFD based on link_info.output_bfd (because
srctemplate is the BFD temporarily using plugin_vec, even after Kwok's
patch link_info.output_bfd is all that's available to base the dummy
BFD on). So we end up with a match from the plugin vector which uses
the pei-i386 vector even though the pei-i386 vector itself does not
match the input object. (In the i686-mingw32 case, as opposed to this
multilib case, pe-i386 is the default BFD target, which would
short-circuit that logic.)
There are two cases of the linker handling inputs with a plugin: they
may be inputs that are also accepted by some non-plugin BFD format, as
here, or they may be a format that would not be recognized at all, as
with some tests in the ld testsuite. In the former case, there is no
need for BFD to accept the objects using the plugin vector, as the
linker has its own logic to allow plugins to claim objects accepted by
some other BFD vector. Thus, this patch arranges for the plugin
vector to have the lowest match priority, and for the priority from
that vector to be used in the relevant case (the attempted match to
the plugin vector results in TEMP pointing to the pei-i386 vector).
Tested for GCC and Binutils testsuites for x86_64-pc-linux-gnu, as
well as verifying that it fixes the observed LTO issue for
x86_64-w64-mingw32.
