From bb1501f2c22c979961b735db775605cccedd98f6 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 1 Dec 2014 17:34:00 -0700 Subject: [PATCH] buildman: Add an option to use the full tool chain path In some cases there may be multiple toolchains with the same name in the path. Provide an option to use the full path in the CROSS_COMPILE environment variable. Note: Wolfgang mentioned that this is dangerous since in some cases there may be other tools on the path that are needed. So this is set up as an option, not the default. I will need test confirmation (i.e. that this commit fixes a real problem) before merging it.
