Oh, that's true. > autoreconf might call > libtoolize with some special --check argument or so, to tell it that > aclocal --install won't be called afterwards.

The last time I thought about this, I wanted to have autoreconf call libtoolize with --check if available. I got stuck on the libtoolize part of the patch because I didn't know the right way to add the serial number checks. If you could add a --check in libtoolize that just sanity checks the setup, then I'd be happy to send a patch for autoreconf that attempts to use the machinery.
