Since changing to libc++ could be a binary incompatible change[*], we should
probably stick to libstdc++ for now and disable C++11 in Qt's build for OS X.
Since we're right now building with GCC 4.2, no C++11 is in use in those
builds anyway, so there's no loss. And there will probably be a gain, by
upgrading the compiler.
[*] it does not affect Qt's ABI, but it might affect other libraries that the
user is compiling against.
