    Make configure error out on missing ghc-tarballs on Windows · 9f7cdfee
    Tamar Christina authored
    Currently checking out the source on windows requires two git
    checkouts. 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.
