virQEMUCapsFindTarget is supposed to find an alternative QEMU binary if qemu-system-$GUEST_ARCH doesn't exist. The alternative is using host architecture when it is compatible with $GUEST_ARCH. But a special treatment has to be applied for ppc64le since the QEMU binary is always called qemu-system-ppc64.

Oh and can you push to appropriate stable branches
