mk for only supported archs
http://fqa.9front.org/fqa1.html#1.2 states the supported archs.
However, clean and nuke also remove build files for 0 (spim) and q
(power).  'mk all' using those archs fails; 'mk kernels' also tries to
build all the kernels, even those which are not supported.  For
example, I tried to build the power arch (qc, qa, ql) and without
surprise it failed (when building dtracy): ...

The patch below skips over non-supported architectures.  Is that
something we want?  This way, 'mk kernels' should work without a
problem (tested on amd64).  Then if someone works on getting those
architectures supported again in the future, they can be added back
in.
