We will have to investigate and make a plan. So this is definitely
a 4.11 issue.

I don't either except that the answer to the recent
problems I have reported to gcc is "I don't know about
arm-elf but arm-eabi works."

That's the way I was leaning since it is an unknown.
But if it had turned out to be trivial, known differences
that had no impact, it was worth considering sooner.
