With the exception of -maltivec and -mspe, other -m options that
select instruction sets always select the entire instruction set. It
seems odd to me that -misa204 should be different in this respect.
Even -maltivec and -mspe select a base set if no other -m<cpu> is
given. As a naive user, I'd expect -misa204 would select all ISA 2.04
instructions.. I guess I'd be happier if you called the option
-membedded.

My copy is 2.04 says maskg is an instruction deleted from that version
of the ISA.
