[tz] make traditional_tarballs fails on macOS for 2022b

[Deborah Goldsmith]

I tried it on macOS 12.5 and while nroff is present there, it fails with the same syntax error in awk. I tried it with a clean fresh clone, too.

To be more clear, "make traditional_tarballs" works fine with a checkout of 2022a on the same system where 2022b fails.
