Port the bug fix for PR 19704 (Missing dynamic relocation against undefined weak symbol) to the SPARC architecture.
* elf32-sparc.c (elf_backend_fixup_symbol): New. * elf64-sparc.c (elf_backend_fixup_symbol): New. * elfxx-sparc.c (UNDEFINED_WEAK_RESOLVED_TO_ZERO): New. (_bfd_sparc_elf_link_hash_entry): Add has_got_reloc and has_non_got_reloc. (link_hash_newfunc): Initialize has_got_reloc and has_non_got_reloc. (_bfd_sparc_elf_size_dynamic_sections): Set interp to .interp section. (_bfd_sparc_elf_copy_indirect_symbol): Copy has_got_reloc and has_non_got_reloc. (_bfd_sparc_elf_check_relocs): Set has_got_reloc and has_non_got_reloc. (_bfd_sparc_elf_fixup_symbol): New function. (allocate_dynrelocs): Don't allocate space for dynamic relocations and discard relocations against resolved undefined weak symbols in executable. Don't make resolved undefined weak symbols in executable dynamic. Keep dynamic non-GOT/non-PLT relocation against undefined weak symbols in PIE. (_bfd_sparc_elf_relocate_section): Don't generate dynamic relocations against resolved undefined weak symbols in PIE (_bfd_sparc_elf_finish_dynamic_symbol): Keep PLT/GOT entries without ynamic PLT/GOT relocations for resolved undefined weak symbols. Don't generate dynamic relocation against resolved undefined weak symbol in executable. (pie_finish_undefweak_symbol): New function. (_bfd_sparc_elf_finish_dynamic_sections): Call pie_finish_undefweak_symbol on all symbols in PIE. * elfxx-sparc.h (_bfd_sparc_elf_link_hash_table): Add interp. (_bfd_sparc_elf_fixup_symbol): New function.
