From e269012c4b919624ca92d80afd1d6a6f5399e041 Mon Sep 17 00:00:00 2001
From: "Yann E. MORIN" <yann.morin.1998@free.fr>
Date: Mon, 19 Dec 2016 18:07:07 +0100
Subject: [PATCH] configure: search for lib with clock_getres()
Like clock_gettime(), clock_getres() is in -lrt for glibc < 2.17.
Add a check for it, like is done for clock_gettime().
