Sorry, but I think the mechanism is fully adequate for any real-life
situation: the developer will first see that configure won't produce
any files, fix that bug by adding AC_OUTPUT, then see the other
automake error.  We don't need to ensure that all errors are
non-followup ones, that is impossible in practice.

I'm thus closing this bug as invalid.

Thanks for the report,
Ralf
