Why don't you put that into a script or make rule that starts with
"git archive $TAG | tar xf - -C tmpdir"?

Yes, please do.  Portability is not an issue inside "if MAINTAINER_MODE".
Unpacking the dist, configure --enable-maintainer-mode + make distcheck
should match what we do for creating the official tarball.
