warnings: be less forceful about a missing subdir-objects option.
This change somewhat ameliorates https://bugs.gnu.org/20699.
* bin/automake.in (handle_single_transform): change
forward-incompatibility message for subdir-objects to be
less draconian and less certain that the change will ever be made.
* t/subobj.sh: message text has changed.
* doc/automake.texi (Program and Library Variables): mention
the unfortunate fact that one directory can clean in a sibling,
subdir-objects notwithstanding.
