Matthew Bauer a9400e64e7 ghcjs: add version to haskellCompilerName This is needed for some cabal2nix stuff in getting the version. Previously we had left out the version but apparently this can cause problems in some scenarios. /cc @elvishjerricco @peti @ericson2314		2018-06-14 11:38:13 -04:00

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.
