right, the thing is that objtool is standalone application like perf,
and before their builds can go the 'fixdep' needs to be there.. that's
a condition to use the tools/build framework

not sure how offensive it'd be to current Makefiles if we come with some
generalized code to do that.. I'll think about it, but I think we might
be better of the way we are now

we have.. it's just the matter who will build it first ;-)
