Its a very good question. As things stand today, there is a one to one
mapping between MACHINE_ARCH and MACHINE, the difference being the
removal of invalid characters for the package namespace. That implies
that no, its not allowed.

The intel boards you mention do something a little different, they
inject a new "arch" into the hierarchy and then several machines share
that common "arch".

I suspect the intel boards you mention do suffer from the issue you
mention in a related way and the fix may be to s/MACHINE/PACKAGE_ARCH/
in DEPLOY_DIR_IMAGE as previously mentioned. The difference is I suspect
they deploy for the first machine built and then not for any other.
Nitin/Darren may be interested in checking into that.

Right, the allarch behaviour is an illustration but not the underlying
problem you need to resolve (although its related).
