ntp checks for presence of sys/timepps.h to determine whether the kernel

installs this header. Without this feature the ATOM clock driver does
not work, and other drivers like NMEA have reduced precision. Remove
the feature non-determinism and increase ntpd capabilities by adding an
explicit dependency.

Could we add this dependent by PACKAGECONFIG?
That was my original intent, but it was rejected as non-deterministic.
