I think it'd be better to have a dedicated macro for what you're trying to achieve (if we need one), instead of full suite of definitions like this. This does not even precisely describe the property you want to capture. We allow targets to customize the set of entry points in a header, so you could hypothetically have a target which defines signal.h, but still does not have all the required libc functions.
