rtems_task Init(
   rtems_task_argument ignored
)
{
   TEST_BEGIN();

   puts( "Init - If coverage enabled, call coverage marker methods" );
   #if defined(RTEMS_COVERAGE)
     start_coverage();
     end_coverage();
   #endif

   TEST_END();
   rtems_test_exit(0);
}

 From looking at the git log, the start_coverage() and end_coverage() 
were never defined in RTEMS. I guess we can remove this test program.
