config.gcc: Reorganize --with-cpu logic.
* config.gcc: Reorganize --with-cpu logic. Set
configure_default_options according to the default CPU, --with-cpu,
--with-arch, --with-tune, --with-schedule, --with-abi, and
--with-float. Check for legal values of various options.
* configure.in: Define configure_default_options in configargs.h.
* configure: Regenerated.
* config/mips/mips.h (TARGET_DEFAULT_ARCH_P)
(TARGET_DEFAULT_FLOAT_P): New macros.
* gcc.c (do_option_spec): New function.
(struct default_spec, option_default_specs): New.
(main): Call do_option_spec.
* config/alpha/alpha.h, config/arm/arm.h, config/i386/i386.h,
config/mips/mips.h, config/pa/pa.h, config/rs6000/rs6000.h,
config/sparc/sparc.h (OPTION_DEFAULT_SPECS): Define.
* doc/install.texi: Update --with-cpu documentation. Mention
--with-arch, --with-schedule, --with-tune, --with-abi, and
--with-float.
* doc/tm.texi (Driver): Document OPTION_DEFAULT_SPECS.
