[WinRT] WASAPI configuration tests skipped

On the current WinRT Qt 5.8 packages no audio devices are recognized. I think that the WASAPI is missing/not set, because the audio/libqt_wasapi.dll is missing:

See file qtmultimedia/src/plugins/plugins.pro
In Qt 5.7.1:
winrt

{ SUBDIRS += wasapi \ winrt }

In Qt 5.8:
win32

{ qtConfig(wasapi): SUBDIRS += wasapi }

winrt

{ SUBDIRS += winrt }
