I think I'd rather the simplest approach of just having the weak
functions print an error and return an error code.  At least for now I
don't think we need to go through the trouble of advertising whether
certain commands are available.  Technically they are available, they
just always fail :-)

And, people don't tend to use objtool directly anyway.

BTW, several of the patches didn't apply cleanly to tip/master, so
you'll probably need to rebase for v2.  There've been a lot of objtool
changes lately.  Peter's been busy...
