Make sure deprecation warnings don't cause errors with -Werror

Browse Source 
It sounds like a good thing to have this warning, but for
future-proofing we can't have it. The system libraries might change
and add deprecation marks (OS X does that often). If they do that, we
don't want poor developers to have to fix all warnings before they can
build Qt again.
