You could specify that AC_CONFIG_FILES comes first, and *_COMMANDS occurrences come later in the order that appears in the source (and do nothing unless the corresponding AC_CONFIG_FILES exists).

The simplest implementation would amount to two m4_append (actually one m4_append plus one _AC_CONFIG_COMMANDS_INIT) in AC_CONFIG_FILES_COMMANDS, and an m4_ifdef in _AC_CONFIG_REGISTER_DEST.
