Bug#965109: libc6: 'semop(1): encountered an error: Function not implemented' in fakeroot under qemu

[Andreas Beckmann <anbe@debian.org>]

Package: libc6
Version: 2.31-1
Severity: important

Hi,

I just noticed some packages recently started failing to build with pbuilder
in qemu (qemu-user-static) foreign arch chroots (on amd64 host) with this error:

dpkg-buildpackage: info: source package xtrs
dpkg-buildpackage: info: source version 4.9d-2
dpkg-buildpackage: info: source distribution unstable
dpkg-buildpackage: info: source changed by G. Branden Robinson <g.branden.robinson@gmail.com>
 dpkg-source --before-build .
dpkg-buildpackage: info: host architecture armhf
 fakeroot debian/rules clean
semop(1): encountered an error: Function not implemented
dpkg-buildpackage: error: fakeroot debian/rules clean subprocess returned exit status 1

I believe that is caused by the the ongoing glibc 2.31 transition,
since that seems to be the component that has recently changed in the sid chroot.
It may also have just exposed a latent bug in fakeroot/qemu.
