I had never tried using CONF=pi3, but I suppose what is really
controlling which kernel is being used is config.txt which I hadn't
looked at closely until you pointed out the image you build has both
kernels.  So I would have to deliberately copy /arm64/pi3 to pi4 to
mess things up, or change config.txt directly.
