* config.gcc (mips*-*-*): Add --with-fpu support. Make single the
default for R5900 targets.
* config/mips/mips.h (OPTION_DEFAULT_SPECS): Handle --with-fpu.
(ISA_HAS_LDC1_SDC1): Set to false for TARGET_MIPS5900.
* config/mips/mips.c (mips_option_override): Report an error for
-march=r5900 -mhard-float -mdouble-float. Use spu_single_format
for -march=r5900 -mhard-float.
