[PATCH v3] examples: linker requires that library dependencies follow use

[Lucas Rangit Magasweran <lucas magasweran ieee org>]

On modern distributions, ld runs with the '--as-needed' option enabled by default, meaning library 
dependencies must come after files that require them. Also, this allows indirect linking so the build 
commands can be simplified.

The alternative is to add the '-Wl,--no-as-needed' gcc option or use the top-level Makefile.

Tested on:
 * Ubuntu 16.04.3 with gcc Ubuntu 5.4.1-8ubuntu1
 * Fedora 24 with gcc Red Hat 6.1.1-3
