Support for a "geode" arch in the distribution packaging
tools was a missing prerequisite to integrate this work
cleanly.

Dennis thought yum about it a while ago, and the rpm part
has recently been upstreamed.

Now I guess all that's left to do is adding a geode subarch
in koji and use it for some selected packages, such as glibc.
We're already planning to do optimization work during the
Update.2 timeframe.

Here's an experimental rpm based on Rob's work ported
forward to glibc-2.7:
