The selector is based on JSON files generated via image.mk. Anything
using legacy image creation won't produce these files.

I don't plan to manually add those files nor creating a legacy JSON
mechanism, hoping it would be accepted in the next point release. Sorry.

I'd say that's an *upstream issue* regarding device naming. My
suggestion is to add (32Bit) or (64Bit) as DEVICE_VARIANT to
bcm27xx/image/Makefile.

The selector must avoid heuristics as this becomes a never ending story
of tedious maintenance.
