Actually the warning is a bug in the do_strip() of kernel build. The vmlinux
image does have the .comment section, but the code that checking if the
.comment section is existed is wrong. Please see the following codes in
do_strip():

		for str in ${KERNEL_IMAGE_STRIP_EXTRA_SECTIONS}; do {
			if [ "$headers" != *"$str"* ]; then
				bbwarn "Section not found: $str";
			fi

			"$CROSS_COMPILE"strip -s -R $str ${KERNEL_OUTPUT}
		}; done


The "*" doesn't have special meaning in the if string test. So it will return
true even the $str is a substring of $headers. How about change the test to:

			if ! (echo "$headers" | grep -q "^$str$"); then

Thanks,
Kevin
