Trying to build happy in a sandbox with cabal-install from git fails.

[Ongy]

I first reported that to happy, I got redirected here. haskell/happy#89 (comment)

Trying to build happy I encountered a problem during the cabal install step.

This is on archlinux with ghc 8.0.2 and cabal from recent git HEAD.

Full log, so you can see what I'm doing. The interesting line is probably:

happy: /tmp/happy-1.19.5/.cabal-sandbox/share/x86_64-linux-ghc-8.0.2/happy-1.19.5/HappyTemplate-arrays-coerce: openFile: does not exist (No such file or directory)
