But not redumpable.

Why couldn't it be redumpable? All that the user should need is a C compiler. That's not unreasonable.

Besides, the problem with a second link is that it might change the
relative positions of symbols within Emac

How could that be a problem? Symbols known to C code are known by their fixed offsets and the second link wouldn't change these offsets, and symbols not known to C code need to be reallocated anyway during loading.
