  There is more info on geode optimizations for GCC and glibc at:
http://wiki.gnashdev.org/wiki/index.php/Building_OLPC_Tools. There is some
minor tweaking of the optimizer for the geode, it's mostly treated as a
pentium class processor. While it could be better, with these patches it's
still better than the default of pentium. Anyway, I'd love to work with folks
that are also into shaving cycles whereever possible.
