Before you laugh, there are people that have done this sort of building in the past as well.  The hardest part, literally, would be to come up with the list of targets.

I am running cross-compile builds on all the 33 failing targets. Like
Mike said, it is only taking a few minutes per target. If there is no
objection, I *will check in* this patch in another 2 hours provided
all 33 targets succeed. This will atleast unblock all targets.
