bind fails with sig11 on start / pthread failure on ARM?

Not so much, the first values for ras_start/end were chosen to be immediate
values, so you could just mov them, but the new one aren't.
Try something like the patch attached instead (untested, I have no arm setup
here, but you'll get the idea).
