Using mktemp -d in specfiles' BuildRoot means that quite a few stray temp dirs 
will start to appear in %{_tmppath}.  For example "rpm -q --specfile 
foo.spec" and "rpmbuild -bs foo.spec" create them, and nothing cleans them up 
(no, tmpwatch doesn't count) - we probably don't want that.

One way to avoid it is mktemp -ud, but it's more racy than plain -d.  I 
think -ud would be a better choice nevertheless.
