GHC (API?) question: GHC Core for Base libraries

[Christopher Done]

Hi Bill,

I use a different approach, using docker, and that's to use a patched
`Main.hs` (https://github.com/chrisdone/prana/commits/master/ghc-8.0/Main.hs)
and compile GHC with that patched file. It's a little unorthodox but
has so far been highly effective.

Here is a repo of a core interpreter I've been dabbling with:
https://github.com/chrisdone/prana

Here I have a Dockerfile that copies my edited version of `Main.hs`
and builds base, ghc-prim and integer-gmp together into an isolated
package database:
https://github.com/chrisdone/prana/blob/master/Dockerfile.ghc-8.0#L56-L114

My Main.hs writes a .prana file for every module. At the end of the
Dockerfile, I export that to a .tar.gz archive:
https://github.com/chrisdone/prana/blob/master/Dockerfile.ghc-8.0#L113

Then I have a set of scripts
https://github.com/chrisdone/prana/tree/master/scripts
To build the image, and one to copy the libraries to the current
directory under `libraries/`.

Hope that's of some help!
