IIRC I've had success using qemu-user-static and schroot and debootstrap to create a powerpc64 (BE) debian chroot that seems to work for me...my system is Ubuntu 20.04 x86_64. Unfortunately, I don't have any handy instructions for how to do that as I did it quite a while ago and I can't remember all the details.
