Peter Xu c6093a05d6 configure: don't warn SDL abi if disabled 
SDL has the same problem as GTK that we might get warnings on SDL ABI
version even if SDL is disabled.  Fix that by only probing SDL if SDL is
enabled.  Also this should let configure be a little bit faster since we
don't really need to probe SDL stuff when it's off.
