From cc835752ae3634acd2d487fdf5152f6075f45aef Mon Sep 17 00:00:00 2001 From: Jamie Iles Date: Fri, 11 Dec 2009 09:21:00 +0000 Subject: [PATCH] perf tools: Allow cross compiling For embedded platforms, we want to be able to build the perf tools on a build machine to run on a different arch. This patch allows $CROSS_COMPILE to set the cross compiler. Additionally, if NO_LIBPERL is set, then don't use perl include paths as they will be for the host arch.
