As far as I am aware, the "make build" phase works identically whether
or not MKUNPRIVED is used, so there's no need for a switch such
as you suggest.  It's the "make install" phase that behaves very
differently, either saving ownership and permissions in the METALOG
(with MKUNPRIVED), or saving ownership and permissions directly in the
inodes of the target files (without MKUNPRIVED).

I think that it would be useful to have a simple way of telling
${TOOLDIR}/bin/nbmake-${MACHINE} to install as if MKUNPRIVED had not
been set at the time the wrapper was created.  I haven't thought enough
about how to do that.
