FWIW, it does that unless you use --force.

What difference does that make from saying: My Automake version is older
than my gnulib version?  What makes this issue different for texinfo.tex
than for config.guess, config.sub, missing, install-sh?

I suppose if you write such a macro to detect presence of options for
Automake, that would be nice to have.  For now, I guess we can put
something like this in our

mydist: dist
        -$(MAKE) $(AM_MAKEFLAGS) dist-lzma

to have `mydist' produce the available formats.
