I can't think of any comfortable way.

Here is an awkward idea, just for your amusement.

If you
  AC_SUBST([AUTOMAKE_OPTIONS])
from configure.ac, then
  AUTOMAKE_OPTIONS = @AUTOMAKE_OPTIONS@
will be the default value of AUTOMAKE_OPTIONS in all Makefiles.  

Automake will then complain that @AUTOMAKE_OPTIONS@ is not a
supported option, and abort...  unless you override
AUTOMAKE_OPTIONS in each Makefile.  You could arrange to define
AUTOMAKE_OPTIONS in all your include fragments.

One annoying problem is that the diagnostic you get when a
Makefile do not include any makefile fragment will refer to the
AC_SUBST definition in configure.ac, not to the current
Makefile.
