From 73b726c25f94c1b15514ed9249b927afdfbbfb94 Mon Sep 17 00:00:00 2001
From: Jussi Kukkonen <jussi.kukkonen@intel.com>
Date: Fri, 7 Aug 2015 10:30:40 +0300
Subject: [PATCH 1/4] Remove redundant compiler sanity checks
AC_PROG_CC already performs sanity checks. And unlike the removed
checks, it does so in a way that supports cross compilation.
Modified from patch by Maarten ter Huurne.
Upstream-Status: Submitted [http://savannah.gnu.org/bugs/?43223]
