From e9628fbd391972d4ffe5882d283d512df7fa705c Mon Sep 17 00:00:00 2001 From: Oleksandr Tymoshenko Date: Mon, 16 May 2016 23:24:36 -0700 Subject: Fix dynamic librariy support detection for platforms without libdl Some platforms (e.g. FreeBSD) do not have libdl, but dlopen and related functions are part of libc. So first check for dlopen in libc, and only if that fails, look for it in libdl.
