From 376737d99dfe7ff0347dcc278e16001573314aa5 Mon Sep 17 00:00:00 2001 From: Nicolas Dichtel Date: Thu, 14 Apr 2016 16:58:32 +0200 Subject: [PATCH] Makefile: reset LD and AR environment variables The goal is to fix the compilation of perf (from linux) when LD or AR variables are inherited from the environment. After the linux upstream commits 5ef7bbb09f7b ("perf tools: Allow to specify custom linker command") and 3c71ba3f80bb ("perf tools: Really allow to specify custom CC, AR or LD") CC, AR, and LD variables are not overridden if they are inherited. In case of a cross compilation, it results in an inconsistent state: CC is overridden but not LD and AR.
