alpha-dec-vms always loads a number of libraries, -limagelib,

ERROR should really be reserved for errors in the testsuite framework,
not just normal errors from the tools under test. Removing use of
perror has been suggested before but without action, over concerns
that some test failures might be missed. This patch removes uses of
perror in ld_assemble, ld_compile and ld_nm, and updates numerous
places that ignored the result of these functions by inappropriately
returning an "unresolved" test status. Net result over my large set
of targets look good, in some cases improving the diagnostics, eg:
i386-msdos -ERROR: tmpdir/script: nm failed
i386-msdos -ERROR: tmpdir/script: nm failed
i386-msdos -ERROR: tmpdir/script: nm failed

This patch makes ld accept and ignore -plugin options when configured
with --disable-plugins. The idea is to allow using a linker built
without plugin support with a gcc built with plugin support. Quite
obviously such a combination won't work if using LTO, but gcc has a
habit of passing a bunch of -plugin and -plugin-opt arguments to ld
even when not generating or linking LTO objects.
Why do I want to do this? Well, it lets me and other binutils
developers answer the question as to whether plugin support breaks
binutils in some areas. Which it does for some targets.
* lexsup.c (ld_options): Accept -plugin and -plugin-opt when
!ENABLE_PLUGINS.

The ld testsuite includes numerous tests that depend on being able to
compile and link programs with the C compiler. Some of these tests
use [which $CC] to check for the presence of the compiler before
proceeding with the test, but run_ld_link_exec_tests and run_cc_link_tests
give ERRORs if compilation fails. Also, even if $CC is defined and present,
it may not be usable due to missing libraries, etc.
This patch adds a new procedure check_compiler_available that attempts
to build an empty program and caches the result. Uses of [which $CC]
are replaced with calls to this procedure, and run_ld_link_exec_tests
and run_cc_link_tests now also guard attempts to use $CC.

run_dump_test proposes an ld action but when trying to make use of it in
a gas test it gave me some Tcl error. It turns out that it references
the check_shared_lib_support procedure and ld_elf_shared_opt variable
both only available in ld-lib.exp. I've thus moved the procedure in
binutils-common.exp and defined the variable needed in the various
default.exp of testsuite that seem to be using run_dump_test.
Since check_shared_lib_support itself references the ld variable not
defined in binutils-common I've defined it from LD in run_dump_test and
fixed LD and LDFLAGS to be defined as expected by run_dump_test in the
various default.exp of testsuite using run_dump_test.

We have three copies of run_dump_test in the testsuite. This is a first
step towards consolidating them.
A few tests use objcopy to convert to verilog or srec output, then
check that output is as expected. Those tests can just as easily use
objdump, keeping the set of dump programs (addr2line, nm, objdump,
readelf, size) separate from utilities under test. That in turn makes
auto-detecting the dump program possible in more places.

When -z separate-code, which is enabled by default for Linux/x86, is
used to create executable, ld won't place any data in the code-only
PT_LOAD segment. If there are no data sections placed before the
code-only PT_LOAD segment, the program headers won't be mapped into
any PT_LOAD segment. When the executable tries to access it (based
on the program header address passed in AT_PHDR), it will lead to
segfault. This patch inserts a GNU_PROPERTY_X86_ISA_1_USED note if
there may be no data sections before the text section so that the
first PT_LOAD segment won't be code-only and will contain the program
header.
Testcases are adjusted to either pass "-z noseparate-code" to ld or
discard the .note.gnu.property section. A Linux/x86 run-time test is
added.

Bring the LD implementation of `run_dump_test' in line with its binutils
and GAS counterparts and report the UNSUPPORTED status for tests the run
of which has been prevented by means of one or more of `target',
`alltargets' and `notarget' tags. Define `skip', `anyskip' and `noskip'
tags, which do not report anything for tests that are not run.
The rationale behind this is that we want to have unsupported tests
reported to ensure that they have actually been attempted and have not
been accidentally suppressed. Then tests which have target-specific
variants that cannot be expressed with a single .d file can make use of
the newly added tags to silently suppress the uninteresting variants.

Implement a more complex way of selecting targets to include or exclude
with `run_dump_test' cases, by extending the syntax for the `target',
`not-target', `skip' and `not-skip' options (with the binutils and GAS
test suites) and the `target', `alltargets' and `notarget' options (with
the LD test suite) to also accept a name of a TCL procedure instead of a
target triplet glob matching expression. The result, 1 or 0, of the
procedure determines whether the test is to be run or not. This mimics
and expands `dg-require-effective-target' from the GCC test suite.
Names of TCL procedures are supplied in square brackets `[]' as with TCL
procedure calls, observing that target triplet glob matching expressions
do not normally start and end with matching square brackets both at a
time. Arguments for procedures are allowed if required.
Having a way to specify a complex condition for a `run_dump_test' case
to run has the advantage of keeping it local within the test case itself
where tool options related to the check might be also present, removing
the need to wrap `run_dump_test' calls into an `if' block whose only
reason is to do a feature check, and ultimately lets one have the test
reported as UNSUPPORTED automagically if required (not currently
supported by the `run_dump_test' options used for LD).

gcc configured using --with-ld always uses that particular version of
ld if it exists. This patch adds a check that the ld version reported
directly from ld-new matches that reported via gcc. I chose to
compare the ld --version output rather than a more strict test (for
example by gcc --print-prog-name=ld), because the version test allows
a user to run the ld testsuite after installing a new ld (in the place
expected by gcc).

PR21287 notes that .init_array is correctly given a type of
SHT_INIT_ARRAY while .init_array.nnn gets SHT_PROGBITS. This patch
fixes that problem, and properly drops warnings from the compiler that
would cause the testsuite to fail. My a44d0bd78 change to check
ld_compile status, necessary to pick up compile errors, also meant
warnings were not ignored.
