commit e4c8659bbb78c98a30dd5e19a4fe27044d33aa85
Author: Peter Trommler <ptrommler at acm.org>
Date:   Fri Jan 15 13:25:38 2016 +0100

    Link command line libs to temp so
    
    Symbols in libraries specified on the GHCis command line are
    not available to compiled modules because shared libraries
    are loaded with local scope. So we link all libraries specified
    on the command line into each temporary shared library.
    
    Test Plan: validate
