[PATCH] adjust .version updating

[Jan Beulich]

(Note: Patch also attached because the inline version is certain to get
line wrapped.)

In order to maintain a more correct build number, updates to the
version
number should only be commited after a successful link of vmlinux, not
before (so that errors in the link process don't lead to pointless
increments).
