bbaddd4bbe PR27441, inconsistency in weak definitions
This makes IR objects use the same logic as normal objects with
respect to what sort of ref/def makes an as-needed library needed.
Testing the binding of the definition is just plain wrong.  What
matters is the binding of the reference.

	* elf-bfd.h (struct elf_link_hash_entry): Add ref_ir_nonweak.
	* elflink.c (elf_link_add_object_symbols): Set ref_ir_nonweak and
	use when deciding an as-needed library should be loaded instead
	of using the binding of the library definition.

b9b204b311 read_leb128 overflow checking
There is a tiny error left in dwarf.c:read_leb128 after Nick fixed the
signed overflow problem in code I wrote.  It's to do with sleb128
values that have unnecessary excess bytes.  For example, -1 is
represented as 0x7f, the most efficient encoding, but also as
0xff,0x7f or 0xff,0xff,0x7f and so on.  None of these sequences
overflow any size signed value, but read_leb128 will report an
overflow given enough excess bytes.  This patch fixes that problem,
and since the proper test for signed values with excess bytes can
easily be adapted to also test a sleb byte with just some bits that
overflow the result, I changed the code to not use signed right
shifts.  (The C standard ISO/IEC 9899:1999 6.5.7 says signed right
shifts of negative values have an implementation defined value.  A
long time ago I even used a C compiler for a certain microprocessor
that always did unsigned right shifts.  Mind you, it is very unlikely
to be compiling binutils with such a compiler.)

0d6aab7776 RISC-V: PR27200, allow the first input non-ABI binary to be linked with any one.
RISC-V only defines two float ABIs, soft-float and double-float, and the
value of soft-float is 0x0.  But 0x0 usually means unknown/default setting
for many targets, and the non-ABI binary, which is generated by "ld/objcopy
-b binary", also has the 0x0 elf header flags, this may be confused.

We probably can define a new unknown/default ABI value to make them more
clear, but that will need more bits in the elf header flags, and also need
to discuss in the riscv psabi spec.

Training linker have a default ABI setting, and can be changed by ld
options or configure options is another solution, like what assemblr
usually do.  So all objects, including the binary files, will have
explicit ABI setting.  But the binary files will no longer be linked
with any object, users need to recompile them with the exactly ABI
they want.  It may be inconvenience sometimes.  Besides, I think linker
doesn't need to know the default arch/abi so far, just set them according
to the linked objects should be enough.

Therefore, without changing the riscv psabi, and keep the non-ABI binary
can be linked with any object, we don't check the ABI flags if no code
section in the PR24389.  Just that we find the first input non-ABI binary
still cannot be linked with others in the PR27200.  This patch fixs the
problem by delaying the elf_flags_init(obfd) check, since the flags of
non-ABI object with no code cannot be copyed to output BFD, we should
skip it, even if it is the first linked object.

However, there is a strange "break" at the end of loop in the PR24389.
The "break" cause the ld testcase "Link with zlib-gabi compressed debug
output 1" fails for rv64gc-linux toolchain, after applying the above
change.  The root cause is that - the "break" make linker only checks
the "first" section of input BFD rather than the entire sections.
I have checked that AARCH64 and ARM both have the "break" at the end
of loop, but ARC doesn't.  I suppose we should remove the "break" like
what ARC do, or use a pair of braces for the if statement.

I have passed the elf/linux toolchain regressions, so the change should
be fine.

1781a9d0f3 nds32_elf_get_relocated_section_contents
nds32_elf_get_relocated_section_contents uses nds32_get_section_contents

9514861402 bfd, opcodes, libctf: support --with-included-gettext
Right now, these libraries hardwire -L../intl -lintl on a few fixed
platforms, which works fine on those platforms but on other platforms
leads to shared libraries that lack libintl_* symbols when configured
--with-included-gettext, and/or static libraries that contain libintl as
*another* static library.  If we instead use the LIBINTL variable
defined in ../intl/config.intl, this gives us the right thing on all
three classes of platform (gettext in libc, gettext in system libintl,
gettext in ../intl/libintl.a)..  This also means we can rip out some
Darwin-specific machinery from configure.ac and also simplify the Cygwin
side.

This also means that the libctf testsuite (and other places that include
libbfd, libopcodes or libctf) don't need to grow libintl dependencies
just on account of those libraries (though they still need such
dependencies if they themselves use gettext machinery).

b209b5a6b8 SHF_LINK_ORDER fixup_link_order in ld
This moves the SHF_LINK_ORDER sorting from bfd_elf_final_link to
the linker which means generic ELF targets now support SHF_LINK_ORDER
and  we cope with odd cases that require resizing of output sections.
The patch also fixes two bugs in the current implementation,
introduced by commit cd6d537c48.  The pattern test used by that
commit meant that sections matching something like
"*(.IA_64.unwind* .gnu.linkonce.ia64unw.*)" would not properly sort a
mix of sections matching the two wildcards.  That commit also assumed
a stable qsort.
