From e51bf208fbd3796238ff4d721e8d070f711f8c56 Mon Sep 17 00:00:00 2001
From: Cristian Stoica <cristian.stoica@nxp.com>
Date: Thu, 10 Dec 2015 12:42:19 +0200
Subject: [PATCH 27/38] use Linux kernel conventions for Makefile variables
The kernel Makefile specifies to use M=... instead of SUBDIR=... for
external modules.
PWD variable is already set in a POSIX system and calling `pwd` to find
it is redundant.
