Hmmm, the build isn't going to work unless a valid sys.mk is found,
and since DEFAULT_MAKESYSPATH is at the end of MAKESYSPATH, if
${PREFIX}/share/mk contains the right stuff, then DEFAULT_MAKESYSPATH
shouldn't make any difference (performance issues aside).

But since bmake was modified to default to ${PREFIX}/share/mk only, 
(at least when built via its boot-strap script) I don't see a particular
problem with this patch.  I'll test it out... (in bmake not pkgsrc).

That's handy to know.

I think we need Todd's input here...
I don't have access to one of these systems, so have to go by the input
from those that do.
