Sorry for start a new mail for I just register to mail list and cannot
reply original mail.

Maybe below change to meta/classes/kernel.bbclass is acceptable
because rebuild of make-mod-scripts is triggered only when kernel is
already cleaned for this case.

do_clean[depends] += "make-mod-scripts:do_clean"
