For a grain of confidence and background - Upstream there is also a follow up fix [1], but that is not needed for your package.
The reason is, that this follow up is only needed if dpdk has no pkg-config, which the 16.11 based package that is in Debian right now already have. [1]: https://github.com/collectd/collectd/pull/2405 -- Christian Ehrhardt Software Engineer, Ubuntu Server Canonical Ltd
