From 2b6da98883ad4d97df3016d89edff4c5cf9c1324 Mon Sep 17 00:00:00 2001
From: Dan McGregor <dan.mcgregor@usask.ca>
Date: Wed, 26 Apr 2017 20:29:41 -0600
Subject: [PATCH 08/24] clang: driver: Check sysroot for ldso path
OE does not necessarily follow the default path for the dynamic linker,
therefore adjust it for OE. Check for the default path, and if it isn't
there, check /lib.
