###
### From topdir, first use multistrap to prepare a raspbian stretch armhf root
### $ sudo multistrap -d multistrap-raspbian-stretch -f native_client/multistrap_raspbian_stretch.conf
###
### You can make a tarball after:
### $ touch multistrap-raspbian-stretch.tar && sudo tar cf multistrap-raspbian-stretch.tar multistrap-raspbian-stretch/ && xz multistrap-raspbian-stretch.tar
###
### Then cross-build:
### $ make -C native_client/ TARGET=rpi3 TFDIR=../../tensorflow/tensorflow/
