Here are three configs which fail.

They have in common:

# CONFIG_PCI is not set

As a tip for the future - always build the default
def/allno/yes/modconfig targets and as many randconfigs as possible when
changing Kconfig dependencies. I've learned that the hard way.

Here are the build failures:

You get the idea...
