SDL2 threads don't work

[jakogut]

When using SDL2 threads, a feature which is currently disabled while building SDL2, a stack overflow occurs.

Test case:

#include <SDL.h>
#include <assert.h>

static int test_thread()
{
	return 2 + 2;
}

int main()
{
	SDL_Thread *thread;
	int ret;

	thread = SDL_CreateThread(test_thread, "Test Thread", (void *)NULL);

	if (NULL == thread) {
		return 1;
	} else {
		SDL_WaitThread(thread, &ret);
	}

	assert(ret == 4);
	return 0;
}

exception thrown: RangeError: Maximum call stack size exceeded,RangeError: Maximum call stack size exceeded

I'm diagnosing the problem, I think this would be a good feature to support.

Looks like you're the generic implementation of both mutexes and semaphores which are implemented on top of each other.

@Daft-Freak Yes, it seems the fix was fairly trivial.
