Yes, I have seen that (maybe you announced it already on the ct-ng
mailing list). I personally don't care enough about AVR32 to spend some
time integrating this in Buildroot, but I've Cc'ed Simon Dawson who
might be interested.

That said, even gcc 4.4 is relatively "old" by these days standards, so
I am not sure it would make a huge difference compared to keeping the
existing gcc 4.2.

Best regards,
