Disable kernel auto local versioning

With this patch, the name of the kernel is always 2.6.23-davinci1
instead of changing with local changes with names such as
2.6.23-davinci1-g723849a8-dirty. At the moment we don't need this
feature and it just create confusion and leave cruft in
/lib/modules, so it's better to keep it disabled.
