* tc-h8300.c (relocation mappings): Remove. Moved to tc-h8300.h.

Browse Source 
(build_bytes): Mark fixups for PCrel branches as signed.  For
        OBJ_ELF, make sure the reloc's offset points to the first byte
        to be modified.
        (md_convert_frag): Update definiton based on BFD_ASSEMBLER.
        * tc-h8300.h (relocation mappings): Add.
