Cannot build ghc-9.0 branch (or older GHC branches) with happy-1.20.0
Attempting to build the ghc-9.0 branch (at commit 5ccf44c6) using happy-1.20.0 yields the following errors:

| ^^^^^^^^^^^^^Downgrading to an earlier version of happy (e.g., happy-1.19.12) is a workaround. As far as I can tell, this issue makes all old versions of GHC unbuildable with happy-1.20.0.
I'm not quite sure what the best way forward is here, but cherry-picking commit fddddbf4 appears to be one possible solution. Thoughts, @int-index?
