Avoid unnecessary bumping of Makefile.in's timestamp.
* Makefile.in (gen_origin): Move to gitlog-to-emacslog.
(emacslog): New variable.
(ChangeLog): Use $emacslog. Don't pass $gen_origin.
(unchanged-history-files): Use $emacslog rather than Makefile.in.
(change-history-nocommit): Store hash in $emacslog.
* build-aux/gitlog-to-emacslog (gen_origin): Move default here.
* admin/update_autogen (changelog_files): Update for the above.
