Fix NORETURN when GCC minor version is 0

The check currently tests if major > 2 && minor >= 1 (since the wanted
attribute functions were likely available since GCC 3.1). That of course
failing if a newer x.0 release of the compiler is used, like GCC 8.0.
So let's fix the check to handle all newer compiler versions correctly.
