Thanks for the comments.
This issue will be fixed by this: https://patchwork.kernel.org/patch/11515997/
and the Makefile will be cleaned up by this: https://patchwork.kernel.org/patch/11515995/
They are parts of the big series of Makefile cleanups. So, I will apply the whole to kbuild tree.
Thanks.
-- Best Regards Masahiro Yamada
