with -k option and never be used without kflag. This confuses
gcc because we set "kflag" at the same time with "kernel", but

Since we can initialize "kernel" to NULL then know if "k" option
is set through determining whether it is still NULL, don't try
to have gcc to guess why we are connecting "kflag" with "kernel"
and use "kernel" directly in place of kflag.
