Ugh, sorry, that's all my bad - I accidentally included a cset in the
latest merge which I didn't mean to, since it was not tested properly yet
(obviously ;).

Now, since it happened anyway:

The plan is to always feed the linker script through cpp - many archs do
it already anyway, so doing it always makes things more consistent.

Andrew Morton also has a patch which needs preprocessing vmlinux.lds on
i386, which is an additional reason, another one is the building in a
separate objdir (That's for later, though)

So, the attached patch finishes this work at least for i386, un-breaking
it.

Linus, please apply.

kbuild: Preprocess vmlinux.lds on i386 as well.

We want do so on all architectures for consistency, and i386 will need
the preprocessing soon anyway.
