When running rebase on multiple DLLs for x86, downwards rollover is now
going back to the top of the 64-bit address space, which isn't right for
x86 images. This patch should restore the previous behaviour of rolling
over (under?) to the top of the 32-bit space instead. I didn't attempt
to deal with upwards rollover due to the following comment.
