I was unclear.  In the case of a static link with a weak undefined
reference to __ehdr_start, that must resolve to 0 normally and not
generate an error.
The case I was talking about was under -shared, when the treatment of
an undefined symbol would normally be to generate a dynamic reloc.
In that case, I think it's acceptable to generate an error instead of
going back and resizing the dynamic sections and everything you'd have
to do.
