configure: simplify CARCH generation madness

Rather than a hardcoded list of only a few select architectures (of the
250+ case statements in config.guess), simply define CARCH to be the
first component of the "target triplet".

This introduces one "regression"- powerpc will no longer become ppc.
However, this is easily worked around in downstream distros if wanted.
This was the only CPU architecture with this oddity so it was felt worth
the price to make this change. Note that 'ppc64' wasn't handled in this
same odd fashion before anyway.
