AIX status?

[David Edelsohn]

	This config.guess confusion is a known problem.  Without
specifying your system configuration and whether the problem was with
binutils or libstdc++ or ..., there was no way to know where to begin
diagnosing your problem.

	The problem is that Power3/Power4 processors have re-introduced
the label "POWER".  When we originally searched for "PowerPC", we ran into
the opposite problem for some class of processors (maybe 601 or POWER/2).
Those processors possibly no longer are important, but it was basically a
catch-22 of choosing one or another processor to be recognized
incorrectly.  The immediate assumption of grepping for PowerPC has
problems.

	The output possibilities are:

POWER
POWER2
PowerPC
PowerPC_POWER3

Because all of the strings are in the format output by the AIX lsattr
command, I think that it would be safe to test for ' POWER' -- note the
space.  That would distinguish POWER (and POWER2) architecture from
PowerPC_POWER3 architecture.
