--- Comment #3 from Bernd Edlinger <bernd.edlinger at hotmail dot de> ---
I think this would do what you want:
Not building gotools for build==host!=target,
but build the gotools for build!=host==target (canadian),
At least the gotools are built without error in the
latter case, but I have not tested if they actually work
on the target.
