Cloning the original bug (BZ#2134183) as the issue resurfaced again, since xz was bumped to 5.2.9 (https://bodhi.fedoraproject.org/updates/FEDORA-2022-63d3579f87).

Description of problem:
Today in our upstream systemd CI I noticed we can't no longer rebuild systemd in the i*86 Rawhide chroot due to unmet dependencies for perl:

```

Expected results:
The perl package should be installable on i*86.
