From 5d8ece87a4105e655da1526baa3753379a56f83d Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb Date: Sat, 4 Jun 2016 22:24:56 +0200 Subject: [PATCH] util-linux: fix scanf fallback detection for uClibc-ng uClibc-ng pretends to be GNU libc 2.2 and then a fallback scanf check is tried, so that libmount is disabled afterwards. Add a fix already suggested upstream. Add librt dependency required for other apps, too.
