kbuild: fix CROSS_COMPILE settings in config.mk
The syntax CROSS_COMIPLE ?= <cross_compiler_prefix> does not work because config.mk is parsed after exporting CROSS_COMPILE. Like Linux Kernel's arch/$(ARCH)/Makefile, we must write as follows: ifeq ($(CROSS_COMPILE),) CROSS_COMPILE := <cross_compiler_prefix> endif Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
