The ARM backend, especially the 2.95.x one, is known to have some
optimization problems. Richard Earnshaw, I believe, is familiar with some
of them. He might have some advice on what is going on here.
2.95.x is what most people will be bootstrapping with.
Mark, I'll leave that machine up, at the same location, during the week.
