Something went wrong when writing the sandbox linker scripts and so we
ended up with a .bss section marker right before the efi runtime sections.

That obviously is a terrible idea, as it may result in overwriting efi
runtime code and data. So let's move the .bss identifier behind the efi
sections.

I think we should revert the patch that changed this, and deal with
each of its changes one by one. As of now, sandbox is broken.

I already sent a patch for this.
