macOS: stub cpuinfo symbols

You are using an invalid method signature.
See https://github.com/pytorch/cpuinfo/blob/512e9d0258212d6759729330b445fa41f4fa0a49/src/api.c#L167.

If you replace a non void function with a void function, then you are producing undefined behavior. In your test the value might be 0, but it could also be any other random uint32_t.

[ChristopherHX]

const struct cpuinfo_package* cpuinfo_get_package(uint32_t index) {
	if CPUINFO_UNLIKELY(!cpuinfo_is_initialized) {
		cpuinfo_log_fatal("cpuinfo_get_%s called before cpuinfo is initialized", "package");
	}
	if CPUINFO_UNLIKELY(index >= cpuinfo_packages_count) {
		return NULL;
	}
	return &cpuinfo_packages[index];
}

You can replace cpuinfo_package with void and return NULL or nullptr, but I like correct signatures.

Ah
You are working around symtoms

	if CPUINFO_UNLIKELY(!cpuinfo_is_initialized) {
		cpuinfo_log_fatal("cpuinfo_get_%s called before cpuinfo is initialized", "package");
	}
