What about AIX? z/OS is technically not officially supported since we don't have CI for it. In practice, as long as it uses basically the same code as AIX, I'm fine with shoving that under the rug, but we should migrate AIX to the new locale API as well in this PR to avoid introducing a chunk of z/OS-only code.
