Ah, good point. I'm not terribly familiar with the things under
tools, so when I saw "objtool" I assumed it was following a standard
pattern for tools.

I can submit a patch for objtool's Makefile. ...or, if it makes more
sense, I can submit a patch to move "objtool" to the scripts
directory. ...or I can butt out of it. :) Which would folks prefer?
