x86: Use zero_undefweak in elf_x86_link_hash_entry
Replace has_got_reloc and has_non_got_reloc in elf_x86_link_hash_entry
with zero_undefweak:
Bit 0: Symbol has no GOT nor PLT relocations.
Bit 1: Symbol has non-GOT/non-PLT relocations in text sections.
zero_undefweak is initialized to 1 and undefined weak symbol should be
resolved to 0 if zero_undefweak > 0.
* elf32-i386.c (elf_i386_check_relocs): Replace has_got_reloc
and has_non_got_reloc with zero_undefweak.
* elf64-x86-64.c (elf_x86_64_check_relocs): Likewise.
* elfxx-x86.c (_bfd_x86_elf_link_hash_newfunc): Initialize
zero_undefweak to 1.
(_bfd_x86_elf_copy_indirect_symbol): Replace has_got_reloc and
has_non_got_reloc with zero_undefweak.
* elfxx-x86.h (UNDEFINED_WEAK_RESOLVED_TO_ZERO): Replace
has_got_reloc and has_non_got_reloc with zero_undefweak.
(elf_x86_link_hash_entry): Likewise.
