What's the purpose of this? Does xxd not generate a consistent name in
out-of-tree builds? If that's the case, a comment to that effect would be

Pumping the regular result of xxd through sed -e
's/\w*\(gen[0-9]*_xml\)/\1/' should work equally well.

I don't think the weird newline that isn't a newline is actually doing
anything for us here.
