x86: Remove the unused _GLOBAL_OFFSET_TABLE_ Since _GLOBAL_OFFSET_TABLE_ may be referenced implicitly on x86, checking ref_regular_nonweak leaves the unused _GLOBAL_OFFSET_TABLE_ in output. This patch checks explicit GOT references instead. ld-i386/discarded1.s and ld-x86-64/discarded1.s are updated to avoid linker optimization which removes GOT references. bfd/ PR ld/22782 * elf32-i386.c (elf_i386_check_relocs): Set got_referenced if _GLOBAL_OFFSET_TABLE_ is referenced or GOT is needed to resolve undefined weak symbol to 0. * elf64-x86-64.c (elf_x86_64_check_relocs): Set got_referenced if _GLOBAL_OFFSET_TABLE_ is referenced. * elfxx-x86.c (_bfd_x86_elf_size_dynamic_sections): Check got_referenced instead of ref_regular_nonweak.
