(The point being that if we have already ensured we write sections in the correct order, then we will only ever need to refer to ordinals of sections that have already been written.) Then we'd be back to a single counter used by the writer for all GOFF symbol records, those that come from sections as well as those that come from symbols.

At first I was a bit confused about this, because the `MCAssembler` sets the ordinal. Well, it seems that the ELF writer overwrites those values. :-) Sure, I can do the same.
