Which makes me wonder why there's such a loose definition of the retval, and what is actually stored in it inside
the func.

Perhaps in a future version of php they want to make it return some sort of number to indicate how much they are different. Or maybe they find out that returning -99999 is faster than -1... Perhaps in the future strcmp('abc','abd') might return 1, because only one letter is different, but strcmp('abc','xyz') would return something completely different. If they keep the definition loose, they can improve the code in the future, without breaking backwards compatibility. This means that a script that now tests if(strcmp($foo,$bar)<0) works now for -1, but it will also work for -42. It's all about reserving the possibility for future improvements.
