* elf32-mn10200.c (mn10200_elf_final_link_relocate): Simplify

    * elf32-mn10200.c (mn10200_elf_final_link_relocate): Simplify
        somewhat.
        (mn10200_elf_relax_section): Correctly compute a symbol's value
        when the symbol is local, but not in the same section as we are
        relaxing.  Implement abs24 -> abs16, imm24 -> imm16 and d24 -> d16
        relaxing.
Another 1.3% size reduction for hello world.  Only relaxing left todo is
imm16 -> imm8 and d16 -> d8 where applicable.
