        * libc/machine/h8300/defines.h : Correct pointer register defines
        for normal mode.
        * libc/machine/h8300/memcpy.S : Use add/sub instead of adds/subs
        for normal mode.
        * libc/machine/h8300/reg_memcpy.S : Likewise.
        * libc/machine/h8300/reg_memset.S : Likewise.
        * libc/machine/h8300/strcmp.S : Likewise.
