It's strictly optional, but… the backtraces are really much better. Specifically, `libunwind` is notably more capable in figuring out function names compared to glibc/libexecinfo `backtrace_symbols()`. Signed-off-by: David Lamparter <equinox@opensourcerouting.org>

The ``libunwind`` library is optional but highly recommended, as it improves
|
|
backtraces printed for crashes and debugging. However, if it is not
|
|
available for some reason, it can simply be left out without any loss of
|
|
functionality.
