Instability on PPC build bots

I just wanted to let the community know that we are in the process of transitioning some of our PowerPC build bots to different hardware and the process is not without kinks. We are working out all the issues but I would like to apologize to developers for the noise caused by some false failure notifications.

We appreciate your patience and are hoping to have all of these bots working on new, better, faster hardware very soon.
