 But if I try to build for anything else, say for R3k or MIPS64, there
will be "-mcpu=r3000" or "-mcpu=r4600" passed and an assembly will fail as
the "standby" instruction won't magically disappear.  That's why
r4k_wait() and au1k_wait() use ".set mips3" for "wait". 

 BTW, "-m4100" and friends are deprecated and their interaction with
"-mcpu=", "-march=" and "-mtune=" is unobvious; I have no idea why they
haven't been banished from the trunk, yet.
