   I suggest that we add MACHINE_KARCH to indicate the kernel architecture this
   machine is using. If I change $MACHINE on the sparc to display sun4{,c,m,d}
   then I'll need more if statements there.


i don't see how you can possibly cleanup the above.  :-)  it doesn't
seem to have much to do with uname but just how sys/arch is.

a MACHINE_KARCH sounds fine to me....or something...just don't make
anything in our system default to using it.  defaults should be
valid for any $MACHINE using $MACHINE_ARCH
