Comment:

 angerman, CC'ing you, because the `gmp` folder exists in `build` because
 of https://github.com/haskell/cabal/pull/4874/commits

 I think the easiest fix we can do for now is just rename the folder we put
 the `config.mk` in, but we should work out a way to dodge this footgun in
 general.
