Explicitly use libstdc++ for non-C++11 static builds
Otherwise the compiler may choose libc++ based on the deployment target,
and we'll end up with broken builds due to the mismatch between the two
libraries, eg:
Undefined symbols for architecture x86_64:
"std::ios_base::Init::Init()", referenced from:
__GLOBAL__I_a in libQt5Qml.a(qv4object.o)
...
"std::ios_base::Init::~Init()", referenced from:
__GLOBAL__I_a in libQt5Qml.a(qv4object.o)
...
"std::__throw_length_error(char const*)", referenced from:
...
This problem is not iOS specific, which is why the logic is moved
to the more generic mac/default_post.prf.
