Prob & Solution: Emacs 21.4 - configure guesses wrong OS for AIX 5.2

In the emacs-21.4 distro, the configure script guesses AIX 3.2 when run on an AIX 5.2 machine.  The problem is that the configure script does not recognize 5.x versions other than 5.0 and 5.1.  AIX 5.2 and 5.3 both exist, and should be accounted for.  The fix is simple.  After implementing this fix, I ran "./configure", with no arguments, and then "make", and it compiled fine.  There are virtually no other GNU products on this machine (autoconf, automake, etc), because it's very difficult to get GPL stuff approved for install anymore.  *sigh*

My guess is that this fix also works on 5.3.  I have a 5.3 box, but it's not ready yet for this kind of test.  I'll get back to you on that.
