Support for Apple iBook G4 #33
Description
After recently acquiring an iBook G4, it may be interesting to support it as a build/runtime target, for Orion.
(It originally shipped with Mac OS X 10.4.11, which I've made a backup of, and I've managed to install Ubuntu 9.04, which is now officially unsupported, but at least allows for installing a GNU toolchain).
