Actually the idea I like best so far is Jason's profile suggestion.
* package.use.mask gcc[pie] in the 13.0 profiles
* generate a new set of profiles 17.0 where it's package.use.forced
* tell people they may have to rebuild world when they switch
-> This would also give us some time to discuss what other changes we might
make with the transition to the new profiles.
-> Also, this means the transition is independent of gcc release timing.
(We just need to be careful since hardened also inherits 13.0, so the setting
must be overridden there. As far as I can see that's already done there
though.)
