There may be a way to use bsd.*.mk to do this, however we just use 
chroots + nullfs mounts.

Basically we buildworld into a directory and then nullfs mount our other 
sources under it, then we chroot to that "build".

I recommend doing this (or even using vms) as it's way too easy to 
introduce contamination from the host build environment otherwise.
