commit e22526a1852a8986afe8926ac538ea2cb4f2a240
Author: Tor Lillqvist <tml at collabora.com>
Date:   Mon Dec 8 09:29:28 2014 +0200

    Don't treat clew as part of an "external" clcc module
    
    There is no obvious authoritative upstream for clew anyway, so it causes
    philosophical problems for distros. For a while, we used to use a zip archive
    from the "clcc" project on SourceForge that included clew.c and
    clew.h. (Before that we also just had clew.c and clew.h in our source repo.)
    
    So, drop the external/clcc module and have clew.c and clew.h in the source
    repo again. But this time clew is in a module of its own, not in sc.
    
    This re-introduces "No need to have OpenCL optional at configure-time"
    
    This reverts commit 764836cb00e8e6dfd2ab48e080a166ec90359e01.
