I think this patch is a fine one, but it makes me wonder whether we
should try to come up with a roadmap for changing the existing,
non-namespaced OVERRIDES into something less prone to namespace
collisions.  As a first step, we could just add namespaced equivalents
to the OVERRIDES in oe-core, i.e.:

MACHINEOVERRIDES ?= "${MACHINE}:machine-${MACHINE}"

etc, and then convert any usages of those within oe-core to use the new
style.  Then at some later date we can come up with a plan to remove the
old ones.
