Actually, no ... it's still after main(), and the constructors run
before.

So I _think_ with the CONFIG_CONSTRUCTORS revert, this will no longer
work (but happy to be proven wrong!), if so then I guess we do have to
find a way to initialize the KASAN things from another (somehow
earlier?) constructor ...

Or find a way to fix CONFIG_CONSTRUCTORS and not revert, but I looked at
it quite a bit and didn't.
