gcc-g++ blacklisted but still showing up in slackpkg upgrade

This has happened a couple times now on different systems/upgrades. Not sure why but maybe it only happens when there is a version bump?
I intentionally blacklist gcc-g++ below since I typically upgrade multilib prior to upgrading -current with slackpkg.
