kbuild: unconditionally clobber include/linux/version.h on distclean
As of v3.7, the UAPI changes relocated headers around such that the kernel version header lived in a new place. If a person is bisecting and if you go back to pre-UAPI days, you will create an include/linux/version.h -- then if you checkout a post-UAPI kernel, and even run "make distclean" it still won't delete that old version file. So you get a situation like this: $ grep -R LINUX_VERSION_CODE include/ include/generated/uapi/linux/version.h:#define LINUX_VERSION_CODE 200192 include/linux/version.h:#define LINUX_VERSION_CODE 132646 The value in that second line is representative of a v2.6.38 version. And it will be sourced/used, hence leading to strange behaviours, such as drivers/staging content (which typically hasn't been purged of version ifdefs) failing to build. Since it is a subtle mode of failure, lets always clobber the old file when doing a distclean.
