From cd69ef88a7cbe5ad404454ed8f491e6b16b4e86f Mon Sep 17 00:00:00 2001 From: Joonsoo Kim Date: Mon, 29 Oct 2012 22:41:06 +0900 Subject: [PATCH] perf tools: Add info about cross compiling for Android ARM Without defining ARCH=arm, building perf for Android ARM will fail, because it needs architecture specific files. So add related relevant information to the android documentation.
