 664         * elf32-frv.c (_frv_emit_got_relocs_plt_entries): Get addend as
 665         argument, so as to not call _bfd_elf_rel_local_sym to compute it.
 666         (elf32_frv_relocate_section): Pass relocation addend in.  Use
 667         original relocation addend to look up the got relocs/plt entries
 668         table.  Do not call _bfd_elf_rel_local_sym.  Don't error out when
