Hello,

The attached (hopefully) fixes the internal error problems Daniel J 
noticed with the MIPS target.  Briefly:

	o	for the dummy static target used during
		initial startup, the function register_raw_size()
		is now defined (so that the regcache.c code can
		use it).

	o	For the mips, the macro REGISTER_RAW_SIZE()
		is no longer defined, instead multi-arch is used.

The basic mips-elf, is now capable of starting up.
