* elfxx-mips.c (_bfd_mips_elf_discard_info): New function, code from
elf32-mips.c. (_bfd_mips_elf_write_section): Likewise. * elfxx-mips.h (_bfd_mips_elf_discard_info): New prototype. (_bfd_mips_elf_write_section): Likewise. * elf32-mips.c (elf32_mips_discard_info): Move to elfxx-mips.c. (elf32_mips_write_section): Likewise. * elf64-mips.c (_bfd_mips_elf_ignore_discarded_relocs): Use it. (_bfd_mips_elf_write_section): Likewise.
