I'm having trouble understanding this build failure [1], which seems to happen only on zani.
pabs mentioned that this is recently upgraded hardware, I'm not sure if that could be related. I have a different bug (emacs related) on zelenka [2] that prevents me from duplicating the problem there. Any ideas for [1]: https://buildd.debian.org/status/fetch.php?pkg=notmuch&arch=s390x&ver=0.29.3-1&stamp=1574860824&raw=0 [2]: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=931651
