From e826574c985a15a500262f2fbd21c7e9259d3d11 Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Tue, 12 Jun 2018 15:00:33 +0200 Subject: x86: Make strncmp usable from rtld Due to the way the conditions were written, the rtld build of strncmp ended up with no definition of the strncmp symbol at all: The implementations were renamed for use within an IFUNC resolver, but the IFUNC resolver itself was missing (because rtld does not use IFUNCs).
