OK, I'm installing QEMU 6.2 and kernel 5.16 from backports on all QEMU
buildds now. Let's see if that helps.
Tested with QEMU 7.0 and glibc patches from [1], still fails.
Need to keep digging.
Did you configure binfmt_misc to preserve argv0 [2] ?
$ cat /proc/sys/fs/binfmt_misc/qemu-m68k
enabled
interpreter //qemu-m68k
flags: POC
offset 0
magic 7f454c4601020100000000000000000000020004
mask fffffffffffffe00fffffffffffffffffffeffff

[2] ``P`` - preserve-argv[0]
Legacy behavior of binfmt_misc is to overwrite
the original argv[0] with the full path to the binary. When this
flag is included, binfmt_misc will add an argument to the argument
vector for this purpose, thus preserving the original ``argv[0]``.
e.g. If your interp is set to ``/bin/foo`` and you run ``blah``
