Google for gold problems, I note that it has been reported to get
"internal error"s during kernel builds - and at least some of them
have been due to ksyms.

So the core problem seems to mainly be that gcc normally itself never
generates any absolute symbols, so the whole ksyms model depends on
things that get almost zero testing in the toolchain.

Oh well.
