This is not consistent: you have 'P' in /etc/binfmt.d/qemu-m68k.conf but
'OCF' in /proc/sys/fs/binfmt_misc/qemu-m68k.

Check "systemctl status binfmt-support.service"

With 'P' when you change the binary you must reload the configuration
because the binary is loaded in memory once when the configuration is
updated.

Thanks,
