There is also evbppc-powerpc64 (aka evbppc64) and macppc-powerpc64 (aka
macppc64). There has been talk (but not much work) about macppc64.

Powerpc is (historically) by default big endian, a little endian variant
would be powerpcel or powerpc64el. The alias names probably would be
evbppc64-el or ofppc64-el.
