John Ericson 5858d7229a ghcjs-ng: The GHC source should be configured with native build inputs
This matters once we start treating GHCJS as cross compilation, as we
should be.

New build system for GHCJS 8.2

ghcjs-8.2 reworked the build system, and now comes with its own small package set of dependencies. This involves autogenerating several sources and cabal files, based on a GHC checkout. callCabal2nix is off limits, since we don't like "import from derivation" in nixpkgs. So there is a derivation that builds the nix expression that should be checked in whenever GHCJS is updated.
