I took this a bit further and I get a working devel/happy package now.
This is still a complete WIP but I wanted to get some early feedback on
the implementation choices as this is my first foray into port-modules.
The patch is currently tested on top of a bunch of hacked ghc-8.10 and
cabal-3.4 patches. I'll have to figure out if there's a way to go back
to ghc-8.6 and cabal-2.4.
Thanks
Greg

Subject: [PATCH] Build devel/happy with cabal v2-install
Passes `make test` and produces a package good enough for ghc build.
