[arch-ports] missing arch arrays

Hey everyone, There are lots of packages in the CVS without an arch array, and makepkg complains about these. I wrote a quick script to add it to all of these packages, but it'd be quite a big change so I'm asking here before actually committing anything. I attached the patch. It's only for extra, I haven't checked core yet. Also, is there any way to generate better patches using cvs? It doesn't seem to generate the same format as "diff -ruN", but I don't know if that really matters or not. Anders
