Regcache changes broke MIPS

I fixed REGISTER_RAW_SIZE() and it died in what appeared to be 
REGISTER_BYTE() .....

At present the architecture gets built three times (!!!):

	o	dummy architecture

	o	default architecture

	o	executables architecture

The first one goes, once the non multi-arch targets are removed.

That is hopefully unnecessary.  Just need to convert a few more MIPS macros.
