libc-config: port __THROW to Ubuntu 4
* lib/cdefs.h (__THROW): Do not use __attribute__ ((__nothrow__))
for GCC 3.3. Problem reported by Jeffrey Walton in:
https://lists.gnu.org/r/bug-gnulib/2019-07/msg00058.html
The GCC 3.3.4 documentation says the attribute should work, but
apparently it does not work on Ubuntu 4’s GCC 3.3. There seems
little point or desire to research this circa-2004 platform further,
so just avoid the attribute there.
