Right that should be a ?= like for COMPILER.

I feel there is something hiding in devel/kf6 as well. A few ports fail
there using base g++ instead of ports-gcc which is not good.

I feel this is one of those where MODULES order is not quite right and so
lang/python sets COMPILER_LANGS before x11/qt6. Again these ports should
be easy to fix.
