Update autoconf version requirement in install.texi.

I noticed that install.texi was out of date with regard to the actual
autoconf version requirement for regenerating configure scripts.  This
patch updates the documentation.

	* manual/install.texi (Tools for Compilation): Update autoconf
	version requirements.
	* INSTALL: Regenerated.
