OK... yes we can fix things up in a subsequent cleanup.

We will need to fix the TOC handling when we go to using multiple TOCs
in the main kernel, with the linker managing the transitions between
TOCs.  Our toolchain guys have been pushing us to do that for years,
because it should make things run faster, but first we'll have to stop
using ld -r to combine objects in subdirectories.
