File 0003-Adjust-build-configuration.patch of Package krb5-mini
From 48abdf7c7b28611c1135b35dfa23ac61899e80b2 Mon Sep 17 00:00:00 2001 From: Robbie Harwood <rharwood@redhat.com> Date: Tue, 23 Aug 2016 16:45:26 -0400 Subject: [PATCH 3/8] Adjust build configuration Build binaries in this package as RELRO PIEs, libraries as partial RELRO, and install shared libraries with the execute bit set on them. Prune out the -L/usr/lib* and PIE flags where they might leak out and affect apps which just want to link with the libraries. FIXME: needs to check and not just assume that the compiler supports using these flags.
