Fixed bug 5411 - config.guess and config.sub outdated

Ozkan Sezer

Our config.guess and config.sub are rather outdated.
Attached new versions of them here.

However, build-scripts/config.sub.patch do not apply
to these new versions: I don't know if and where that
patch is still needed.

build-scripts/config.sub.patch
