This recipe was ported from another layer, which had special handling for rpi. OE-Core doesn't have 'rpi' override, doesn't define 'vc4graphics' DISTRO_FEATURES and overall, BSP-specifics should be handled in downstream layers, not in OE-Core.
Thats fine, however, this will regress rpi BSPs, so either send a patch to add it via a bbappend to meta-raspberrypi or open a ticket so someone can get it done
