 cabal clean has a problem on Windows and Unix with NFS that causes it to
 fail when using a custom `Setup.hs`.  The problem is that we compile
 `Setup.hs` to `dist/setup/setup`, and then invoke `dist/setup/setup clean`
 which is supposed to remove the whole of the `dist` tree, including the
 running binary.  This causes problems on Windows where running binaries
 can't be deleted, and also on NFS where deleting the running binary leaves
 a `.nfs` file behind, preventing the parent directory from being deleted.
