We already know MACHINE_ARCH != TARGET_ARCH in Makefile.inc1 and already do
different things based on it. But to be honest, I'd think there'd be times
I'd absolutely want to build them all, and other times I wouldn't which
strongly suggests some kind of knob specific for cross building the
port/pkg-based kernel modules. We could then pass that knob into the kernel
builds which would then not try to guess whether or not to build
LOCAL_MODULES...
