I think we were missing a proper announcement for GCC 8, and maybe we were not
aware of the amount of code changes needed in third party packages.  So maybe we
should have had in GCC 8 a configure option to make that the default behavior,
announce it in the release notes, ask for testing using that option, and do the
defaults change in GCC 9.  We could do that for GCC 10/11, or just bite in the
apple and now fix all packages builds.
