Ok I didn't know about that possibility so please go ahead and use
this alas table :)

Well I was under impression that config.sub typically doesn't care about
vendor field in the tuple, i.e. what makes sense is "arc-*".

And "oe" vendor (which is used for OpenEmbeddeed toolchains) is just
a corner case together with others (even more often used ones):
 - arc-buildroot-linux-uclibc-
 - arc-snps-linux-
 - arc-linux- etc.

That said I'd keep "arc-unknown-linux-" if possible.

Thanks for your prompt reply!
