Bad news!
This patch is still having problems, see the Autobuilder recently build
(link below). This is on MUT with the updated binutils, I am not sure
if that is part of the problem or not, but binutils was working before.
Partially it's failing with binutils-cross-canadian-<target arch>
Dropping from mut for now, sorry.
Sau!
