I was just thinking that Tristan had wanted to make the branch last
week, and this seems like a major change to do at the last second. My
only concern is it may require some time to shake out any issues.

>> And doesn't GCC already pass -z relro by default anyway where it's supported?

> However, -z relro has been enabled in Fedora since

Ah, right. I forgot it was a distro thing. (That's at least an
argument in your favor, showing there's less potential for
destabilization.)

If you're going to make the change in ld, we should probably also make
it in gold as well. I believe -z relro is fine on all targets
supported by gold.
