The ghc binary distribution contains a 'pwd' binary that's broken on systems running a Red Hat kernel and causes the build to fail. To remedy that problem, we replace that binary with Nix's 'pwd' program before running configure.

Unfortunately, the same problem occurs again with 'installPackage', so as of
now, GHC cannot be installed on Red Hat.
