Laurent helped me debugging and the problem is that Debian has its own binfmt-support
packages which competes with systemd-binfmt with the former not setting the preserve
flag.
It works when writing the configuration into /proc manually:
root@nofan:~/qemu> echo -1 > /proc/sys/fs/binfmt_misc/qemu-m68k
root@nofan:~/qemu> cat /etc/binfmt.d/qemu-m68k.conf > /proc/sys/fs/binfmt_misc/register
root@nofan:~/qemu> chroot /local_scratch/sid-m68k-sbuild/
(sid-m68k-sbuild)root@nofan:/# sh -c 'echo $0'
sh
(sid-m68k-sbuild)root@nofan:/#
