On SPARC the field tv_usec of 'struct timespec' is not a 'long int', but only a regular int. In this case the format string is incorrect and will trigger compiler warnings. Avoid the warnings by casting to 'long long', similar to how it is done for the tv_sec and what the other similar selftests are doing.
