 Hmm, right, I'd forgotten about INSTALLTMP.  With that in mind I think
 you may be correct.  We shouldn't need WORLDTMP at all.

 If it can be done without adding much more complexity it's probably
 worth doing.  I'm a bit skeptical that it will be easy to get the built
 world to actually work in the general case where things in INSTALLTMP
 depend on a new libc but it should be possible.
