* config.gcc (powerpc*-*-* | rs6000-*-*): Add
rs6000/option-defaults.h to tm_file. Support cpu_32, cpu_64,
tune_32 and tune_64.
* doc/install.texi (--with-cpu-32, --with-cpu-64): Document
support on PowerPC.
* config/rs6000/rs6000.h (OPTION_DEFAULT_SPECS): Move to ...
* config/rs6000/option-defaults.h: ... here. New file.
(OPT_64, OPT_32): Define.
(MASK_64BIT): Define to 0 if not already defined.
(OPT_ARCH64, OPT_ARCH32): Define.
(OPTION_DEFAULT_SPECS): Add entries for cpu_32, cpu_64, tune_32
and tune_64.
