    Just tried this with the same effect.

    Could it be your version was already -mylocalver?

    Please note that you have to actually *change* the local
    version, otherwise almost nothing is recompiled.
    Just a touch does nothing.

    Actually, the directory kernel/ is not recompiled (so the subject is a
    bit misleading) , but a huge number of files in drivers, filesystems, sound,
    lib and net directory - are.
