From de28c15daf60e9625bece22f13a091fac8d05f1d Mon Sep 17 00:00:00 2001 From: Bobby Powers Date: Tue, 21 Apr 2015 19:19:41 -0400 Subject: tools lib api: Undefine _FORTIFY_SOURCE before setting it Some toolchains (like Hardened Gentoo) define _FORTIFY_SOURCE in the built-in, default args. This causes perf builds to fail with: :0:0: error: "_FORTIFY_SOURCE" redefined [-Werror] : note: this is the location of the previous definition cc1: all warnings being treated as errors To avoid this, undefine _FORTIFY_SOURCE before (possibly re-)defining it in tools/lib/api. v2 applies cleanly on top of already pulled kbuild changes for 4.1-rc1.
