    Add -fwhole-archive-hs-libs
    
    We're building a demo to show how to hot-swap Haskell code in a
    running process, and unfortunately it wasn't possible to convince GHC
    to generate the correct linker command line without this extra knob.
    
    Test Plan:
    Tested it on a hot-swapping demo (which is not released yet, but will
    be shortly)
