Outdated config.{guess,sub}

[happz]

config.guess, being a bit old, makes it impossible to build pcp from upstream sources on "stranger" architectures, in my case aarch64 and ppc64le. If there's no reason for keeping the current one - and I wouldn't be surprised if there were such reasons, I haven't been playing with autoconf & stuff for a long time, and pcp has a long history and wide set of supported environments, maybe there are some compatibility issues - I'd suggest fetching a newer copies of config.{guess,sub}.
