From: Jamie Iles Date: Fri, 11 Dec 2009 09:21:00 +0000 (+0000) Subject: perf tools: Allow cross compiling X-Git-Tag: v2.6.33-rc1~280^2~12 X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=cc835752ae3634acd2d487fdf5152f6075f45aef;p=~emulex%2Finfiniband.git 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.
