[PATCH] examples: gcc linker requires library depencencies come after they are needed

[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,--as-needed' gcc option or use the top-level
Makefile.

Tested on:
 * Ubuntu 16.04.2 with gcc Ubuntu 5.4.1-8ubuntu1
 * Fedora 24 with gcc Red Hat 6.1.1-3
