* elf-bfd.h (SYMBOL_REFERENCES_LOCAL, SYMBOL_CALLS_LOCAL): Move from
elf32-ppc.c. Add ELF_LINK_FORCED_LOCAL check.
* elf32-ppc.c: (SYMBOL_REFERENCES_LOCAL, SYMBOL_CALLS_LOCAL): Delete.
(allocate_dynrelocs): Use SYMBOL_REFERENCES_LOCAL for dynreloc check.
(ppc_elf_relocate_section): Likewise.
* elf64-ppc.c (allocate_dynrelocs): Likewise.
(ppc64_elf_relocate_section): Likewise. Use for .got relocs too.
(ppc64_elf_adjust_dynamic_symbol): Don't assume symbols with .plt
relocs need no other types.
* elf32-i386.c (allocate_dynrelocs): Use SYMBOL_REFERENCES_LOCAL for
dynreloc check.
(elf_i386_relocate_section): Likewise. Use for .got relocs too.
(elf_i386_finish_dynamic_symbol): Use SYMBOL_REFERENCES_LOCAL for
.got relocs.
