    Preliminary bindist rule (#555)
    
    * Preliminary bindist rule
    
    For now, we only ship `<build root>/{bin, lib}` and the few make build system
    related files that are needed to support a simple
    
    ```
    ./configure [--prefix=PATH] && make install
    ```
    
    workflow. The current binary distributions of GHC support a wider range
    of parameters, but I figured it would be a good thing to start with this
    and enhance it as we all see fit and perhaps using feedback from GHC HQ
    (@bgamari in particular) and bindist users.
    
    * document binary distribution rule in README
    
    * sdist-ghc -> source-dist, Rules.Bindist -> Rules.BinaryDist
