Make make-temp-[file|dir] fully resolve $*TMPDIR
Make make-temp-[file|dir] fully resolve $*TMPDIR

This prevents problems when $*TMPDIR is a symlink and, say, is
used someplace to make a path relative to it. If the symlink is not
the same level as the actual temp dir, the relativenes will have
too few/too many steps in it.
