Heh. Why one ever going to bloat $(srctree) to add more "dontdiff" and
such, where build is supporting dirty output?

any reasons to have multiple files for localversion(s), in $(objtree)
also? Exept one, that somebody used to use it, mm-tree doesn't btw.

As i opposed to Romans's "make" solution, because it wasn't obvious, i
agree current has heavy `find', but what else you can propose? I think,
it's not make's job after all.
