I have a patch that make the built-in.o files into thin archives (same
as archives, but the actual objects are replaced with the name of the
original object file).  That way the final link has all the original
objects.  I haven't checked to see what the overheads of doing it this
way is.

Nick Piggin has just today taken my old patch (it was last rebased to
v4.4-rc1) and tried it on a recent kernel and it still seems to mostly
work.  It probably needs some tidying up, but you are welcome to test
it if you want to.
