Add suse-xsl-stylesheets and pkgconfig(libxslt) BuildRequires,
needed in order to build man pages.
When investigating why gnome-software fails to launch I found this over at fedora...
Seems we need to add our own appstream data now.
# install AppStream data for Fedora
%__mkdir_p %{buildroot}%{_datadir}/app-info/xmls
%__cp %{SOURCE1} %{buildroot}%{_datadir}/app-info/xmls
# decompress and install AppStream icons
%__mkdir_p %{buildroot}%{_datadir}/app-info/icons
cd %{buildroot}%{_datadir}/app-info/icons
%__tar xvzf %{SOURCE2}
cd -
