In my experience, QEMU system emulation works better than user-mode
emulation so an alternative that I believe would work (though it would
be slow) would be to set up QEMU VMs for armhf, aarch64 and powerpc64le
(virt-manager is a convenient GUI to set these things up) and use them
for offloading.

Not all aarch64 processors can run armhf code, but many can. This can be
seen in the "CPU op-mode(s)" field of lscpu. E.g.:
$ lscpu
Architecture: aarch64
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Little Endian
CPU(s): 32
On-line CPU(s) list: 0-31
