From 87f88b28ac01b6449463f00b660fe7416d7f9a55 Mon Sep 17 00:00:00 2001
From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
Date: Sat, 10 Nov 2012 18:53:03 +0100
Subject: [PATCH] Let the configure script find getrpcbynumber in libtirpc
The getrpcbynumber() function may not be available in the C library,
but only in the libtirpc library. Take this into account when checking
for the existence of getrpcbynumber() and getrpcbynumber_r().
