This patch requires a further updated cctools to work properly.  You
can get it from

Ideally this would all be conditional on cctools version, but
failing that, it would be helpful to mention this dependency in
the building-from-source docs.

It can't be conditional on cctools version without having specs conditional on that version, which seemed like a lot of work for no point (since you already have to upgrade to -528, going -528.5 doesn't seem like it would be any extra burden).

You can build GCC, I think, with the previous cctools. You just can't use -mcpu= with a non-default setting and no other flags.
