I don't have much of an opinion on the renaming, but the overrides part
will cause an unacceptable level of namespace pollution.  As it stands,
everybody will suddenly get "Unknown" in their OVERRIDES and this is not
at all desirable.

If you must add these kinds of things to the default OVERRIDES then they
need a suitable namespace prefix, for example something like
soc-family-${SOC_FAMILY}.  (Alternatively, put it in your own DISTRO
configuration where you can do whatever you like.)
