So now allow any arch to select the > option, continue defaulting to N. Alan Modra recommended this approach several years ago, and I think Stephen was the first to implement this for the kernel. It would be good to have the rational whay ar is better than ld -r included in the commit message for later reference. I also recall that using ar gave some small kernel size reductions from last time we played with this. This info could also be nice to give a rough idea of the impact. Added Alan to list of receivers. Sam
