Cloning a repository with mercurial results in a bus error:

> Thread 1 "" received signal SIGBUS, Bus error.

This could be a known bug in zstd on this hardware:

https://github.com/RPi-Distro/repo/issues/179

The bug has been fixed in zstd 1.4.8, but the mercurial package
embeds the older version 1.4.4.

The standalone package in pkgsrc-2022Q1 is already at 1.5.2

>How-To-Repeat:
Use mercurial on 32bit evbarm.
