Did you have CONFIG_INET set? I'm attaching my full .config. This is
on vanilla Ubuntu 16.10.
I did see the same error when building with `CONFIG_STATIC_LINK=y`.
Note that I also, separately, ran into a linker problem, though I
believe it is unrelated to this patch
(though perhaps is related to the problem you're seeing?):

I'd also be happy to provide you with ssh access to the machine that
I'm seeing this on if that
would be helpful.
