So what bothers me about this (and the original patch) is that TMPDIR
has special meaning to bitbake and the conflict with patch's temporary
directory is unfortunate.  Maybe a better solution is to change
meta/lib/oe/patch.py to set TMPDIR when invoking patch so the changed
TMPDIR is constrained to the patch process and nothing else.
