Properly handle relocs against absolute symbolsusers/hjl/pr19818
Relocations against absolute symbols in shared object should be resolved at link-time if symbols are bounded locally. For PC-relative relocation against absolute symbols, they should be converted to non-PC-relative relocation in target backend. If conversion can't be performed, target backend should detect it and issue an error. This patch only fixes x86 backends. bfd/ PR ld/19818 * bfd-in.h (bfd_elf_record_link_assignment): Add a bfd_boolean. * bfd-in2.h: Regenerated. * elf-bfd.h (elf_link_hash_entry): Add def_linker and def_linker_abs.
