It's possible with a caveat: in my experience both the object tree and the
source tree have to have *exactly* the same path on the build host and the
destination.  You can't (for example) build with MAKEOBJDIRPREFIX set to
something, then copy src to /usr/src and obj to /usr/obj on the destination
and have installworld work.
