WIP: haskell libraries

So far our few Haskell packages (e.g. shellcheck) are statically compiled. This is of course not ideal and we should try to move it to dynamic libraries.

For this effort @kdaudt and I packaged some basic Haskell libraries.

It's been stuck in a branch of mine for some months and before I would continue I like to get some opinions on this. Are we packaging this right? Should we package all GHC libraries separately or split it out of the main GHC package like in this branch? Etc.
