Bleah.  Maybe we could live with this and teach distdir how to
merge the two directories, i.e., install all the files from
$(srcdir)/foo/ in $(distdir) and overwrite them with all the
files from $(builddir)/foo/.  We discussed this in the past, but
it seemed useless.  Now we have a case where it would be helpful
(although $(builddir)/foo/ is empty).
