This has two advantages: * 1) Saving about 20M on the size of the resulting tags file (which are used currently to store the absolute path of the file names rather than the relative one) when KBUILD_OUTPUT is not set. * 2) Keeping the tags file valid when the directory is renamed. No change is done for who does make tags O=..., if this is wanted (I would find that incommodous and non-typical for a developer, but anyway I've not ruined functionality in that case).
