Not really: it's been in config/ompi_get_version.m4 before, I just

I know that some BSD versions try to use their m4 for autotools.
At least OpenBSD has some patches in their ports to not disallow
it. Since I have little experience as to how far this actually
works, I figured to rather not remove the comment. I'd really
like to know about systems and hear about experience with non-GNU
m4 and autotools, though. If it's easy to keep them compatible
with it, I believe we should not hinder it.
