This was causing release-cross to fail hydra eval, so it hasn't been building for the last few days. So note that although ghcjs still does not build, this fixes eval so the jobset can proceed. Verified with `hydra-eval-jobs pkgs/top-level/release-cross.nix -I nixpkgs=.` |

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.
