Oh *igitt*!  There has to be a better way than this, I think.  

What about having bsd.subdir.mk take an arbitrary ${SUBDIR} and
just divide it up internally?  Having to manually break your subdir
list up in to 4 categories really loses as a general mechanism,
though I will indeed try your patch temporarily just to see what
effects it has on build time. :)

Thanks.
