deb-s3 arch patcher

#!/bin/bash

# This file watch APT for changes in stable / main
# that are added for ALL architecture but not i386 and amd64
# This is a bug from deb-s3, that need every build to provide
# -a amd64, as they push file to s3 repository.
#
# check: https://github.com/krobertson/deb-s3/issues/20
