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



Hi Lucas,

The patch is broken due to line breaks.
Could you resend it?

Thanks,
Thomas
