Mmm.  Mips is defined in the Makefiles?  But the Makefiles are generated
from the Imakefiles and the templates, and the templates test against Mips.
There is a problem here somewhere.

It may be possible to get around it by making sure that imakemdep.h defines
the correct symbols for ccimake/imake when imake is initially built.
Then you could rely on a specific, single symbol in Imake.tmpl.
But again, this depends on the contents of BOOTSTRAPCFLAGS being well-defined
for the initial configuration.  Chicken/egg?
