    PR21432, buffer overflow in perform_relocation

    The existing reloc offset range tests didn't catch small negative
    offsets less than the size of the reloc field.

        PR 21432
        * reloc.c (reloc_offset_in_range): New function.
        (bfd_perform_relocation, bfd_install_relocation): Use it.
        (_bfd_final_link_relocate): Likewise.
