Guard against cases where GCNOS would be empty, resulting in failed builds

There are some Makefiles that install headers explicitly, without creating
programs, e.g., `usr.sbin/amd/include`. In order to support this case moving
forward, specifically test for _GCNO_SRCS being non-empty, then set GCNOS
appropriately.
