This suggests that geoclue (the main package) has files which link
directly to the gypsy and gps libs respectively; rpmbuild detects this
and sets automatic dependencies.

>From looking at your spec file, you include the
%{_libexecdir}/geoclue-{gpsd,gypsy} files not only in their subpackages
but also in the main package (by way of "%{_libexecdir}/geoclue-*"). To
avoid that, you should either list all other files in that directory for
the main package or use this construct:

%files
...
%{_libexecdir}/geoclue-*
%exclude %{_libexecdir}/geoclue-gpsd
%exclude %{_libexecdir}/geoclue-gypsy
