You can actually do both. You can license under GFDL *OR* CC-BY-SA, or 
under GFDL *AND* CC-BY-SA (the latter provided that the licenses are 
compatible, which may or may not be the case). In the first case a 
derivative work may be under either of the licenses, or again under both 
of them. In the second, it would have to be under both.
