linux-kernel has had this discussion recently so this is all I'm going
to say about this in public. I'll be glad to engage in private
correspondence though.

No, I don't think so. The key part here is 'failing to run make dep'.
Changing __SMP__ in the Makefile, or changing CONFIG_SMP in the
configuration process, would give the same result.

Vague plan #1: build the .ver files explicitly at 'make dep' time,
as they are built now, but do not ever rebuild them during
'make vmlinux'. This doesn't solve this problem but at least it
gets rid of a lot of useless hairball dependencies which are supposed
to solve problems like this but DON'T.
Vague plan #2: separate compilation. No more .ver files. When foo.o
is compiled, its external symbols get type tags from type information
in foo.c and the files that foo.c includes, not from bar.c which is
over in some other directory!
