One-byte bools for 64-bit Darwin

[Stan Shebs]

Still another tidbit for 64-bit Darwin; bools are supposed to be
one byte in size, leaving 32-bit Darwin as the sole config in all
of GCC with 4-byte bools.

        * config/rs6000/rs6000.c (rs6000_override_options): Make 64-bit
        Darwin default to one-byte bools.
