    imagebuilder: exclude metadata for profiles that have no kernel
    
    Device profiles that specify 'DEFAULT := n' are being included
    in the imagebuilder metadata, specifically in .profiles.mk, even
    though there is no kernel built for the device.  This results in
    'make info' showing the device as valid, but then 'make image
    PROFILE=xxx' failing with 'No rule to make target xxx-kernel.bin ...'
    
    We exclude these profiles from the imagebuilder, avoiding these
    errors.
