This most probably means some of the code running before relocation uses
BSS; see below.

This is normal and should not have any negative impact as long as code
that runs before relocation does not access BSS -- and it should not,
since BSS only exists after relocation.

Weird. Can you provide all necessary info for duplicating these two builds?

If that's a patch to remove the overlay in the .lds, it's a Nak from me
already.
