This would only work for tarballs, though, no? Otherwise we'd need to
commit the generated files, which is tricky because the location
depends on where the build-dir is located, and would probably not play
well with different developers having different versions, leading to
variance in the generated result.

I don't really think this would work for us in Mesa. We no longer
generate the distribution using autotools since we switched to Meson,
we just do git archive these days.
