Add a new majors.powerpc. This was cobbled together from the majors

files of all the different powerpc ports (except amigappc).  It should be
compatible with sandpoint and macppc.  It is compatible with evbppc minus
one device (gtmpsc).

To convert a port to use this file rather than a local one, delete your
majors file, and edit your files.port to point to this instead.  (I will
follow up with a MAKEDEV fix to support this)
