kbuild updates for 3.2

Hi Linus,

this is the main part of kbuild for 3.2. It's rather boring this time:
- Fix to keep _shipped files if the user removes them to force a rebuild
- make distclean does not remove empty files, should someone create one again :)
- Save one make invocation in make prepare
- genksyms won't checksum structs defined inside the current C file
- a couple of minor fixes

The following changes since commit 322a8b034003c0d46d39af85bf24fee27b902f48:
