I built core-image-sato for qemuarm and it appears to work fine.  Are there
any other typical methods/scripts which invoke nativesdk-qemu or
qemu-native besides runqemu?  runqemu works fine for qemu-native, but
runqemu doesn't work for me within the sdk (missing python fnctl module
dependency).  Instead I have tested nativesdk-qemu by directly invoking
qemu-*.

Thanks
