Comment (by luite):

 Unfortunately the fix breaks cross compilation due to a hardcoded
 `WORD_SIZE_IN_BITS` dependency in `TysWiredIn`. If the cross compilation
 target has a different word size than the build machine, the types become
 inconsistent.

 (This makes GHCJS unusable with a 64 bit GHC 8.0.1rc2; it fails to compile
 `ghc-prim`)
