ghc: use CXX=c++, not CXX=cxx

Otherwise attempt to build ghcHEAD from local checkout fails as:

    $ nix build -L --impure --expr 'with import ~/nm {}; haskell.compiler.ghcHEAD.overrideAttrs (oa: { src = ./.; patches = []; nativeBuildInputs = oa.nativeBuildInputs ++ [ git ]; })' --keep-failed
    ...
    ghc> checking C++ standard library flavour... ./configure: line 11487: /nix/store/r7r10qvsqlnvbzjkjinvscjlahqbxifl-gcc-wrapper-11.3.0/bin/cxx: No such file or directory

I think 'cxx' is not provided by stdenv.
