Reviewed-by: Cole Robinson <crobinso at redhat.com>

I like the look of the colors and I agree it speeds up visually scanning
the configure output. But I'm neutral on whether adding more m4 to the
build system to facilitate it is worth it. So I'll abstain from giving
ack or nack on those.

If you push the first two independently you may want to strip mention of
colour from their commit messages
