It would not surprise me at all that there is a dependency, if we have
not had a better way to report the 64bit entry point.  I just wanted to
make the context clear as that was confused in the discussion.

Note that having a 32bit entry point at offset 0 is as much of an ABI.

I am surprised that there are legitimate reasons to bulk up the 32bit
entry point code before the 0x200.  Everything that we are doing at that
point is architectural.
