- Replace gnome-common with autoconf building the package.
- Add gnome-session-logging-to-systemd-journal-configurable.patch
(boo#979498, bgo#768982). Add an autoconf switch to control if
the logs of gnome-session and its child processes should be send
to systemd journal, or to the legacy ~/.xsession-errors-$DISPLAY
when disabled.
For SLE, disable logging to systemd journal.
