d30v relocation fix

[Richard Henderson <rth at cygnus dot com>]

D30v is a RELA target, so there's no point in this chicanery.
This allows us to pass gcc testsuites.


r~

        * elf32-d30v.c (bfd_elf_d30v_reloc): Don't modify section
        contents when performing a partial link.
        (bfd_elf_d30v_reloc_21): Likewise.
