This is for interop with a C/C++ extension, right? Do this test in that
extension's C/C++ code to expose the right dtype. As far as I know, this is
not something determined by the hardware, but the compiler used. Since the
compiler of numpy may be different from your extension, only your extension
can do that test properly.
