I dropped this patch because it autogenerates files which were
previously part of the repository. This causes git checkout to
complain about overwriting existing files when we want to checkout
earlier versions.

How about creating this patch like this:

- create (and commit) a include/config-empty.h
- link to the board specific config.h if it exists or to
  config-empty.h if it doesn't exist.
