Add support for the newworld apple macintosh (PPC). This has been
tested on the powerbook 2000 only. It only adds support for
generic ieee1275 functions, console and disk support. This should
be easy to port to other architectures with support for Open
Firmware.
* configure.ac: Accept the powerpc as host_cpu. In the case of
the powerpc cpu set the host_vendor to ieee1275. Make sure the i386
specific tests are only executed while building for the i386.
