From d7399bd56c8fc7c58af79ef91dc67382cc23eb47 Mon Sep 17 00:00:00 2001
From: Richard Purdie <rpurdie@linux.intel.com>

Subject: base.bbclass: Rework staging function to use a DESTDIR style
 configuration based on the data from the do_install step. This falls back to
 any standard do_stage function if defined, see the mailing list for more
 info.
