No one has ever asked, and there is nothing built into the code to do
it.  I suppose you're asking to mount /usr/src and /usr/obj from the
host machine, and simply do the make world bit?

I suppose you might be able to do this using the preJailBuild Hook.
With /usr/src already mounted, mount /usr/obj under ${jail}/obj.  We are
already passing NO_CLEAN to the make world process, so it should reuse
most of what's been built.
