Trying to build 188

UPDATE:

the quick fix for my issue was to mount the directory first before unsure ran

	local unshare=()
         sudo mount -o bind ${BUILD_DIR}/proc ${BUILD_DIR}/proc
	# Configure a new namespace
	if [ -n "${IN_NAMESPACE}" ]; then
		unshare+=(
			# Create a new cgroup namespace
			"--cgroup"

			# Create a new mount namespace
			"--mount"
			"--propagation=slave"

			# Create a new PID namespace and fork
			"--pid"
			"--fork"

			# Create a new time namespace
			"--time"

			# Create a new UTS namespace
			"--uts"

			# Mount /proc so that the build environment does not see
			# any foreign processes.
			"--mount-proc=${BUILD_DIR}/proc"

			# If unshare is asked to terminate, terminate all child processes
			"--kill-child"
		)
	fi
