    Fix unlit by placing it under lib/bin/ instead of bin/ (#591)
    
    A nicer fix would involve patching GHC to not just look under
    $libexec/ but also under the directory where the GHC binary itself lives
    (bin/ for hadrian), so that we can leave all binaries under bin/.
    
    Addresses Trac #15132.
