[Haskell-cafe] Cross-compiling GHC

[David Johnson]

One (simple?) solution is to use the Nix package manager. Integer-simple
GHCs were recently added (available on both Darwin and Linux afaik). After
downloading the nix package manager, simply run:

*nix-shell -p haskell.compiler.integer-simple.ghc802*

The above command will put you into a shell with an integer-simple GHC-8.0.2

For more info on nix and haskell, this is a good guide:
https://github.com/Gabriel439/haskell-nix

Along with what is mentioned in the nixpkgs manual.
