    configure on Windows now downloads a mingw distribution on the fly if needed.
    
    Summary:
    Also, migrated away from the rubenvb mingw distribution to a more up-to-date
    and semi-official mingw-builds. Updated the version of gcc to 4.8.3.
    
    This change obviates the need for a ghc-tarballs repository.
    
    Also removed use of an embedded perl (also from ghc-tarballs) since it is provided by msys2.
