SCENARIO XML file has included RELEASE or DEBUG info already, so if RELEASE is not specified in make command, Makefile should not override RELEASE info in SCENARIO XML. If RELEASE is specified in make command, then RELEASE info in SCENARIO XML could be overridden by make command. The patch also fixed a issue that get correct board defconfig when build hypervisor from TARGET_DIR; Tracked-On: #4688 Signed-off-by: Victor Sun <victor.sun@intel.com>
