How do you build base with your own compiler?

[Christopher Done]

I did try that first. I did a cabal unpack and ran ./configure, but
sadly it failed with "internal error":

If you have e.g. a docker image that it's known to build inside of,
that would be awesome. I'd much prefer that over the whole compiling
GHC rigmarole.

Ciao!
