Mac: Ensure that C++11 is always used when linking against a static Qt build
If Qt was built with C++11, it links to libc++, and we need all projects
that use Qt to link against the same library.
Technically, we could do QMAKE_LFLAGS += -stdlib=libc++, but that hasn't
been tested enough without also enabling C++11, so we keep the
relationship between the two for now.
