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.
