- Run spec-cleaner:
+ Add pkgconfig BuildRequires.
+ Use %make_install instead of %makeinstall.
+ Add %defattr(-,root,root) to the -lang package.

- Use %_smp_mflags for parallel build and limit fdupes to not work
across common partitions. Replace old-age $RPM_* by %-macros.

- Add gsm-bsc1020294-add-resources-scrollbar.patch: add a
scrollbar to the resources tab (bsc#1020294, bgo#778697).

- Update to version 3.23.92:
+ Updated translations.
- Drop gnome-system-monitor-linking.patch, gnome-common
Buildrequires and call to autoreconf: Fixed upstream.

- Update to version 3.23.91:
+ Smooth chart setting should only affect cpu chart.
+ bgo#778776 fixed broken wnck option.
+ Updated translations.
- Add gnome-system-monitor-linking.patch: Fix build with
-Wl,--as-needed.
- Add gnome-common Buildrequires and call to autoreconf, as above
patch touches the build system.

- Drop pkgconfig(libwnck-3.0) BuildRequires and no longer pass
--enable-wnck to configure, it currently leads to segfaults
(bgo#778776).
- Drop obsolete clean section.
