Tor Arne Vestbø b32a6384b3 iOS: Don't warn about using C++11 extensions
Qt uses a lot of minor C++11 extensions such as long long, commas at the
end of enumerator lists, and extra ';' outside of a functions, and not all
of these can be silenced, so we build without warnings for C++11 extensions,
since we plan to enable C++11 at some point anyways.
