Using a different way to link the kernel would also help us with the remaining allyesconfig problem on ARM, as the problem is only in 'ld -r' not producing trampolines for symbols that later cannot get them any more. It would probably also help building with ld.gold, which is currently not working. What is your suggested alternative? Arnd
