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?
