I've talked about polyglot ATS/Haskell builds previously, but I wanted to show off the results of all this work without so much didactic focus.

This is actually robust enough to distribute: we do have to add a dummy file dist-newstyle/lib/empty in order to allow it under extra-lib-dirs, but this rube goldberg build passes the Hackage matrix CI. It has the downside of bringing in quite a few dependencies, but it avoids the need for hand-packaging ATS.
