Teach objtool about STT_NOTYPE -> STT_FUNC+0 sibling calls. Doing do allows slightly simpler .S files. There is a slight complication in that we specifically do not want to allow sibling calls from symbol holes (previously covered by STT_WEAK symbols) -- such things exist where a weak function has a .cold subfunction for example. Additionally, STT_NOTYPE tail-calls are allowed to happen with a modified stack frame, they don't need to obey the normal rules after all.
