I am a little uncomfortable about adding a new feature to a release branch, but this is not a major configuration and there were previous delays, so this is okay.

Thank you very much. I appreciate your ack!
This gives us a stable compiler for powerpc64-freebsd. Trunk is also ok, but there we have the ups and downs of a development snapshot. (Currently the many failures which are also present on powerpc64-linux.)
