Btw, I've spotted interesting difference between clang and gcc specs.
Unlike gcc, clang spec does not define
QMAKE_LFLAGS_NOUNDEF += -Wl,--no-undefined

As a result, qt5-gui was failing on 9.2 with gcc due to this flag:

Stop in /usr/ports/x11-toolkits/qt5-gui.

It could be built with clang, but then than it has run-time problem with
undefined symbols.

It turned out that libxcb in ports were built without xkb support,
kwm has already enabled it by my request.

I wonder if clang spec should have this flag too.
