From: Darren Hart <dvhart@linux.intel.com>
Subject: [PATCH rt-tests RFC 4/6] Makefile: Support user supplied CFLAGS and LDFLAGS
Date: Thu, 22 Mar 2012 02:14:04 +0100
Accept user supplied CFLAGS and LDFLAGS, overwriting the
Makefile supplied versions. This can cause the build to
fail if the user does not provide at least what the Makefile
defines, but so be it.
