Regression with latest glibc update

Seems like a recent glibc 2.37 -> 2.38 update has broken the build.

Comparing the last successful run and the first failing one shows

fakechroot -- fakeroot -- chroot /builds/archlinux/[MASKED]/build /usr/bin/systemd-sysusers --root "/"
Assertion 'path_is_absolute(p)' failed at src/basic/chase.c:566, function chase(). Aborting.

Although the issue is most likely caused by the following packages:

Good:

extra/fakechroot                           2.20.1-2          0.15 MiB       0.05 MiB

core/glibc                    2.37-3                47.20 MiB       9.91 MiB

Bad:
