    Description

      when building qt with cmake definition QT_QMAKE_TARGET_MKSPEC=linux-clang-libc++, the build passes, but building a simple test project with qmake fails with a lot of linker errors:

       

      libQt6Core.a(qthread_unix.cpp.o):(.data+0x0): undefined reference to `typeinfo for __cxxabiv1::__forced_unwind'
/usr/bin/../lib/gcc/x86_64-linux-gnu/9/../../../../include/c++/9/bits/stl_tree.h:366: undefined reference to `std::_Rb_tree_increment(std::_Rb_tree_node_base const*)'
etc.
