From a9b02de8b79de44ee8f4a0506b65a62f38999bd8 Mon Sep 17 00:00:00 2001 From: Eric Wong Date: Mon, 18 Jul 2016 10:22:08 +0000 Subject: configure.ac: stronger test for pthread linkage We need to test linkage of pthread_create and pthread_join, as pthread_mutex_* and pthread_key_* functions do not need extra linkage under FreeBSD 10.3, leading to a false-positive of the empty case.
