I just realized that this gets a LOT easier with the syscall tapset instead:

probe syscall.nanosleep, syscall.compat_nanosleep ?
{
	if (target_set_pid(pid()) && $rqtp->tv_sec == $1)
		target_set_report()
}

We generally assume that debuginfo is installed for running the testsuite, so let's not focus anymore on problems that aren't related to the thing we're trying to test...
