I think it's ok. It's not going to cause any _subtle_ failures, it's
going to cause very clear "oh, now it doesn't build" errors.

No?

And binutils 2.23 is what, 7+ years old by now and apparently had
known failure cases too.

But if there are silent and subtle failures, that might be a reason to
be careful. Are there?
