MAKEALL supports this, but doesn't default to it, today.  I'm wondering
if we ought to make it the default for all non-single board builds.  The
winning point is right around boards-to-build == `grep -c processor
/proc/cpuinfo` and I think is right around setting NBUILDS to that
value, both on consumer multicore and heavy-duty 32/64 core boxes.
