[Bug 206348] x11-toolkits/qt5-gui : clang++ used with -mcpu=cortex-a7 -mfloat-abi=softfp results in: undefined reference to `qt_convert_rgb888_to_rgb32_neon( . . . )

(In reply to Tobias C. Berner from comment #2)

My attempt to build a modern x11-toolkits/qt5-gui still reproduces the notice
about convert_RGB888_to_RGB32_neon being missing (see
image/qimage_conversions.cpp:2968's error notice below), as well as producing
other notices for undefined references:
