I've just realized that $(AUTOMAKE) can be run from any
subdirectory.  This means we should setup AUTOMAKE_AMFLAGS in
each directory, or use an AC_SUBST.  Not very cunning.  (OTOH,
we can just do `AUTOMAKE="$AUTOMAKE -Wall" in the configure.ac.)

A similar issue exists when one wants to pass extra options to
Autoconf (except $(AUTOCONF) is run only from the top directory).

Besides, this kind of setup affects only runs from the
rebuild rules, not user runs from the command line (unlike
AUTOMAKE_OPTIONS).

What about introducing an new configure macro, AC_WARNINGS, and
change Autoconf and Automake to honor it?
