From 31e88f06af7ab787d8fe0c1ca625193e1799e167 Mon Sep 17 00:00:00 2001
From: Matt Madison <matt@madison.systems>
Date: Wed, 13 Sep 2017 08:12:04 -0700
Subject: [PATCH 3/7] make.bash: better separate host and target builds
Fore OE cross-builds, the simple checks in make.bash are
insufficient for distinguishing host and target build
environments, so add some options for telling the
script which parts are being built.
