This is what I ended up with.  All tests pass, but as I mentioned in a
previous email, very few tests run in the container.  This blocks the
outer variables from coming in, while letting the test itself set them
again if needed.

I'm not sure what kind of test we could run in the container to make
sure we're *not* accidentally using the build-tree file, though.
