commit e8fd61862ae572c7d470acdbcc95eff97de0dc54
Author: Edward Z. Yang <ezyang at cs.stanford.edu>
Date:   Wed Mar 11 14:53:17 2015 +0100

    Update Cabal submodule to latest 1.22 snapshot
    
    This changes the library file name format
    
    NOTE: This patch originally updated to Cabal HEAD, but was reduced to
          update to Cabal 1.22 HEAD by hvr as this is needed in order to
          update the filepath submodule to version 1.4.0, and subsequently
          to be cherry-picked into the ghc-7.10 branch
    
    Signed-off-by: Edward Z. Yang <ezyang at cs.stanford.edu>
    
    (cherry picked from commit 838d8044896b6544d8c80c2ab5de63d97220f06c)
