Update automake config

[aaronjwood]

This resolves a bit of an obscure issue for me. Here's what's happening:

I'm trying to compile a project from source that uses glog. This project needs to be compiled for ARM (aarch64) and the way I'm running this is inside of a container (Docker) on an x86 machine but that has binfmt_misc setup on the kernel to handle ARM binaries through qemu-arm-static. The container starts with a scratch image and just applies Ubuntu's core ARM64 image on top. In the end everything inside is emulated through qemu to mimic an isolated ARM environment.

When the project goes to build its version of glog it runs into:

checking build system type... ./config.guess: unable to guess system type

This script, last modified 2007-07-22, has failed to recognize
the operating system you are using. It is advised that you
download the most up to date version of the config scripts from

  http://savannah.gnu.org/cgi-bin/viewcvs/*checkout*/config/config/config.guess
and
  http://savannah.gnu.org/cgi-bin/viewcvs/*checkout*/config/config/config.sub

If the version you run (./config.guess) is already up to date, please
send the following data and any information you think might be
pertinent to <config-patches@gnu.org> in order to provide the needed
information to handle your system.

Updating config.guess and config.sub from the latest versions here http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess;hb=HEAD and here http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD resolved the issue.
