LD/ELF: Unify STB_GNU_UNIQUE handling
Take STB_GNU_UNIQUE handling scattered across targets and gather it in
the generic ELF linker. Update test suite infrastructure accordingly.
bfd/
* elf-s390-common.c (elf_s390_add_symbol_hook): Remove
STB_GNU_UNIQUE handling.
* elf32-arc.c (elf_arc_add_symbol_hook): Likewise.
* elf32-arm.c (elf32_arm_add_symbol_hook): Likewise.
* elf32-m68k.c (elf_m68k_add_symbol_hook): Likewise.
* elf32-ppc.c (ppc_elf_add_symbol_hook): Likewise.
* elf32-sparc.c (elf32_sparc_add_symbol_hook): Likewise.
* elf64-ppc.c (ppc64_elf_add_symbol_hook): Likewise.
* elf64-sparc.c (elf64_sparc_add_symbol_hook): Likewise.
* elf64-x86-64.c (elf_x86_64_add_symbol_hook): Likewise.
* elfxx-aarch64.c (_bfd_aarch64_elf_add_symbol_hook): Likewise.
* elfxx-mips.c (_bfd_mips_elf_add_symbol_hook): Likewise.
* elf32-i386.c (elf_i386_add_symbol_hook): Remove function.
(elf_backend_add_symbol_hook): Remove macro.
* elflink.c (elf_link_add_object_symbols): Set `has_gnu_symbols'
for STB_GNU_UNIQUE symbols.
binutils/
* testsuite/lib/binutils-common.exp (supports_gnu_unique): New
procedure.
* testsuite/binutils-all/objcopy.exp: Use `supports_gnu_unique'
with the `strip-10' test.
ld/
* testsuite/ld-unique/unique.exp: Use `is_elf_format' and
`supports_gnu_unique' to qualify testing.
