Right. We actually have to take some special steps in the buildfarm
client script to clean up files generated in the tree by vpath builds so
we have a clean repo on the next run.
But arguably packagers should be building from tarballs anyway rather
than from CVS, in which case the build shouldn't put anything in the
source tree.
