commit f78df87c3857c128c9126f1979fbacf84ac5cd1a

    Fix rts.cabal.in
    
    On Windows the FFI library is called `libCffi-6` instead of `libCffi`.
    This needs to be reflected in `rts.cabal.in` as otherwise we cannot
    properly `copy` and `register` the RTS package on Windows.
    
    See https://github.com/snowleopard/hadrian/issues/567
    
    Test Plan: Build GHC using Hadrian. Make build system does not use
    `rts.cabal.in`.
