elf32-mips howto table

[Richard Henderson <rth@cygnus.com>]

The howto lookup in relocate section is incorrect.  The 
howto entries aren't all in a flat table.

        * elf32-mips.c (mips_info_to_howto_rel): Split out switch to ... 
        (mips_rtype_to_howto): ... new function.
        (_bfd_mips_elf_relocate_section): Use it.
