makeinfo version check when compiling emacs-cvs

[Steve Wen]

Hi, I compiled emacs cvs unicode-2 branch today, and found the configure
progress cannot continue because a error says I'm not having texinfo
>=4.6, although it is 4.11 installed here. I looked into the code in
configure and fix it with these:

--8<---------------cut here---------------start------------->8---

I'm not sure is it a bug or something, if it is, please fix it, thanks.
