7b951eed4d * 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.

	* reloc.c: Document BFD_RELOC_M32R_SDA16.
	* bfd-in2.h,libbfd.h: Regenerated.

Reduces code size by about 2.5% for hello world.
