One for the GHC sources and one for the GHC-tarballs. This patch will make configure issue an error if compiling under windows and the GHC-tarballs folder is missing. On failure the user is told which command they need to run to get the tarballs or if they want configure to handle it for them configure provide the `--enable-tarballs-autodownload` flag. Test Plan: 1. make sure ghc-tarballs folder is not present 2. run ./configure which should fail giving an error that tarballs is missing and how to get it 3. run ./configure --enable-tarballs-autodownload and the tarballs should be downloaded and configure finishes 4. rerun the command in 3, no new download should be done. 5. run configure without --enable-tarballs-autodownload, configure should finish correctly.
