Subject: We can't use ${WORLDTMP}/usr/{include,lib} for the compat layer. 
 This is because we populate these directories later, and a subsequent
 -DNOCLEAN build may fail.  So, we put them in
 ${WORLDTMP}/build/usr/{include,lib} instead and adjust Makefile.boot.

Again, this works on -stable and -current, but might break older
versions.
