Revert "Always look for automake scripts in /usr/share, not in %{_datadir}"
    
    Automake installs into %{_datadir}/automake-%{api_version}, thus SDL
    needs to refer to the location using %{_datadir}. Diverging the values
    would bring chaos into the distribution.
    
    Please talk to automake maintainer first or beter ask Fedora Packaging
    Committee for help.
