kbuild changes for v3.15-rc1

Hi Linus,

please pull these kbuild bits for v3.15-rc1:
- Cleanups in the main Makefiles and Documentation/DocBook/Makefile
- make O=... directory is automatically created if needed
- mrproper/distclean removes the old include/linux/version.h to make life easier when bisecting across the commit that moved the version.h file

Thanks,
Michal
