I think this actually makes it more likely to highlight differences, but
either way, the tests I ran did highlight a raft of issues and it seems
to be good enough to find several problems. I've sent enough fixes to
make the new selftest pass.

Sounds good.

FWIW you can run the new test with:

oe-selftest --run-tests sstatetests.SStateTests.test_sstate_sametune_samesigs

in case that isn't clear. It doesn't rely on building anything so is
comparatively fast.
