Yes, you could use SKIP_MAIN_UNDEFINED if it was a test of gettimeofday.

The test in question, however, is the test of delay injection, it just
happens to use __NR_gettimeofday because it was the most convenient way to
implement the test.  If clock_gettime is the only universally available
method of time retrieval nowadays, the test should use it instead.
