otaku% make -f /etc/src.conf -VMODULES_OVERRIDE

...however i checked and tinderbox *does* ignore src.conf and make.conf. the
_.* log files show that modules were being build which are not returned by
the commands above.

i think having this flag would be very useful, because it would force people to
make sure their include dirs are correct.
