kf6-kconfig 6.8.0 test failure on sparc64

[Petter Reinholdtsen <pere@hungry.com>]

While trying to track down why lsdvd failed to run its test on sparc64,
I went down a rabbit hole that ended up with the build failure of
kf6-kconfig 6.8.0 on sparc64.(sid_sparc64-dchroot)pere@stadler:~/kf6-kconfig-6.8.0$ QT_QPA_PLATFORM=offscreen gdb ./obj-sparc64-linux-gnu/bin/test14qml
