Hi Richard,
This patch adds support for the -mmcu option to gcc. Okay to commit?
Thanks,
Catherine

* config/mips/mips.opt (mmcu): New option.
* config/mips/mips.h (TARGET_CPU_CPP_BUILTINS): Define
_mips_mcu whenn TARGET_MCU.
(ASM_SPEC): Pass mcu options to the assembler.
* doc/invoke.texi (MIPS Options): Document -mmcu and -mno-mcu.
