It's only reasonable to assume that gcc matches sprintf if gcc is the
native (vendor-supplied) compiler for the platform. That's not the
case on gaur. It used to be very very commonly not the case, though
I think a lot of vendors have now abandoned their proprietary compilers.
If we were to test for this at all, I think we'd need to make the test
separate from the one for sprintf's behavior.
