config.guess/config.sub files to be identical.  Previously, we had three
different versions of the guess files - now they are the same.

I attempted to merge in ASF changes that were marked and still needed.
Please verify that these work on your platform.  (Particular attention
is required for the IBM platforms.)

Part of PR 7818 stems from the fact that the bundled expat did not have an
included config.guess/config.sub.  Therefore, it would take the config.guess
from the system.  Icarus's autoconf/libtool is very old (2.13/1.3.5).  The
machine that was used to roll 2.0.32 had a recent autoconf/libtool which
explains the behavior that Sander saw in the PR.  Therefore, we now
explicitly provide a config.guess/.sub for the bundled expat so that
all of the versions are in sync.  This should minimize configuration
problems.

pcre was using a config.guess that was imported when Brian made the 3.9
import.  It did not have the Apache modifications, but seems to have
had the Darwin changes.  Go figure.  Sync it up as well.
