Disable objc_msgSend stubs in static libs to maintain Xcode < 14 compat
Xcode 14's Clang will emit objc_msgSend stubs by default, which ld from
earlier Xcode versions will fail to understand. Disable these stubs
explicitly for static libs, for as long as we support Xcode < 14.
See https://github.com/llvm/llvm-project/issues/56034
Pick-to: 6.5
Fixes: QTBUG-112820
