I prefer to do flavors without ifs at the moment

USES= [...] qt:${FLAVOR:S/qt//} [...]
_USE_QT_qt5=	buildtools:build qmake:build linguisttools:build \
		concurrent core gui multimedia network opengl qmake sql svg \
		widgets xml
_USE_qt_qt6= 	5compat base multimedia svg tools
USE_QT=${_USE_QT_${FLAVOR}}

see for example audio/pulseaudio-qt/Makefile

[jbo]

Improve flavor handling.

^minor nit-pick, I would put the build-deps at the end here... but that really does not matter :)
