config: Add tests for modules-desired features
this adds configure tests for features that modules can take advantage of -- and if they are not present has reduced or fallback functionality. gcc/ * configure.ac: Add tests for fstatat, sighandler_t, O_CLOEXEC, unix-domain and ipv6 sockets. * config.in: Rebuilt. * configure: Rebuilt.
