I've though about this on and off over the years, and would actually
like to see src/make.conf or src/world.conf and remove the /etc
dependecy. The major reason is that I often have more than one
src tree on a build system and I have to screw around with /etc/make.conf
if build environments are different.
This can be implemented by a simple backtrace up the tree from any
level looking for make.conf, terminating either when we find one,
or when we hit /.
