    score howto special_function final linking output bfd access
    
    Like commit 804439b4d7a8, avoid segfaults when the hack to access
    the output bfd won't work, eg. when the sym is absolute.
    
            * elf32-score.c (score_elf_gprel15_reloc): Return bfd_reloc_undefined
            when output_bfd cannot be determined from the symbol.
            (score_elf_gprel32_reloc): Likewise.
            * elf32-score7.c (score_elf_gprel32_reloc): Likewise.
