Old GHC versions from old nixpkgs revisions

Works on my machine (x86_64-linux).

How to use: take a look at default.nix. Invoke this package with the system that it should build for. This is pure, so it can be used in flakes.

The following GHC versions and the corresponding last-known-to-build nixpkgs revisions are included, most are cached in cache.nixos.org:

• 6.10.4
• 6.12.1 (uncached)
• 6.12.2 (uncached)
• 6.12.3 (uncached)
• 7.0.2 (uncached)
• 7.0.3 (uncached)
• 7.0.4
• 7.2.1 (uncached)
