Removing -mtune=xscale is enough to pass that (the same source builds fine for
other devices I'm using), using -mtune=arm926ej-s also works.

Thanks for investigating. I'll run a bootstrap on arm with the backported
patch.

After looking at it more closely: Mikael, are you sure the revisions are right?
It seems to me that r199813 is just the backport of r199188.
Can you please double-check the revision that fixes this current ICE?
Thanks,
Kyrill

Oops. The ICE was fixed by r198462, r199188 is the followup. Sorry about that.
