* Makefile.am (changelog_etc, syntax_check_exceptions): Define.
(EXTRA_DIST): Use.  Remove names that are now automatically
included: build-aux/git-version-gen, build-aux/vc-list-files.
* build-aux/ChangeLog-2007: Rename from */ChangeLog.
* doc/ChangeLog-2007: Likewise.
* lib/ChangeLog-2007: Likewise.
* m4/ChangeLog-2007: Likewise.
* po/ChangeLog-2007: Likewise.
