From bd9f25c593a140acb15d3fd3fc7f66d091e1a898 Mon Sep 17 00:00:00 2001
From: Chris Parsons <cparsons@google.com>
Date: Wed, 20 Jan 2016 20:06:28 +0000
Subject: Add a DEVELOPER_DIR make variable to genrules to propagate the apple
 xcode environment variable DEVELOPER_DIR to commands.

If $(DEVELOPER_DIR) is included in the genrule command, we bootstrap the XCODE_VERSION_OVERRIDE environment variable to the command.
The contract with the actual action executor is, if XCODE_VERSION_OVERRIDE is present in the environment, to additionally bootstrap the DEVELOPER_DIR absolute path to the command.
