* internal.h (H8/300 specific relocs): Add comments better

        explaining what each reloc is used for.
        (R_MOV16B1, R_MOV16B2): Renamed from R_MOVB1 and R_MOVB2.
        (R_MOV24B1, R_MOV24B2): Renamed from R_MOVLB1 and R_MOVLB2.
        (R_MOVL1, R_MOVL2): New relocs.
More changes for the H8/300 relaxing linker.  HMSE.
