I most definitely did run "make clean" first.
However, since that same test didn't fail when run like this

    ./gnulib-tool --create-testdir --with-tests --test fflush

and I knew something was wrong with my set-up.

I tracked it down to the fact that that tree had been built using
autoconf cache values (--cache=FILE), and *they* were stale.
Clearing that cache and rebuilding made the problem go away.
