[Jens Petersen]

commit a964910d3dd31f03fd04972699097f1064a5cfc7
Author: Jens Petersen <petersen at redhat.com>
Date:   Wed Dec 3 20:40:47 2014 +1000

    add a static subpackage and common subpackage
    
    bcond static
    
    probably only good for ghc-7.8 since non-intel archs
    do not have shared libs before that.
