You are missing one or more 'options' or 'device' specifications from
the configuration file.

The "dependencies" involving configuration options are not well documented, 
And there are a few options that are -not- really 'optional', despite their
name.  <wry grin>

You should start with the 'GENERIC' kernel config, and make 'small' changes,
*testing* with a compile attempt after each such change, until you get to
the kernel configuration you need.

>From the error messages, it appears you are missing 'options LIBALIAS',
a keyboard-related device, and something to do with the clock.
