Thanks. I will rework the patch to use this function.

The plan is to drop arch/$(SRCARCH)/defconfig and solely rely
on KBUILD_DEFCONFIG.
And I see KBUILD_DEFCONFIG thus for a "make defconfig" the
DEFCONFIG_LIST becomes unused.

But I guess your point is that we should dropt KBUILD_DEFCONFIG
entirely and rely on DEFCONFIG_LIST instead.

I will try it out.

OK.

Thanks for your feedback.
PS. I will post the updated patches in the weekend. Not that they
are difficult but I'm on the way out of the door for a few days
travelling.
