  * Add --supported-languages support to dummy-ghc
  We used to call the bootstrapping compiler to get its --supported-languages
  but that doesn't work when it doesn't support all the extensions that we
  need. In particular, compiling the new bytestring which needs NamedFieldPuns
  broken when building with 6.8.2.
  There's now a rather ugly sed script to extract the extensions from
  DynFlags.hs.

    M ./utils/ghc-cabal/ghc.mk -4 +28
