We can't include this one, since we need to be able to work with
automake on RHEL-5.

I think perhaps we should wire this into the autogen.sh
script. People are used to just cloning a repository and
running autogen.sh to get things setup, so it would cause
unneccessary confusion to also require them to run bootstrap
seprately.

We have a few custom non-gnulib rules in Makefile.maint, for
checking use of non-reentrant safe functions, and banning use
of asprintf() in favour of virAsprintf(). Is there a good place
to hook those into the stock gnulib Makefile.maint. Perhaps we
could just abuse Makefile.cfg for this since its included anyway?
