  The addends are *in* that array of bytes, at the offset indicated by the
arelent->address field (what I referred to as 'destination' in my last
post).

Yep.  The symbol will point to externData and the offset/addend will be the
distance to the accessCounter member.

However, the whole point (about REL vs RELA) is that in this case, the
addend is not in a field in the arelent reloc struct, but is in the bytes of
the input section indicated by the address.
