Re: Bfd/binutils inconsistency re: *UND* and *ABS* and relocsagainst dummy (STT_NOTYPE) symbol entries in elf symbol tables!?

objdump presents a somewhat canonicalized symbol table, and the special
undefined symbol has no name, which is probably why it's not shown here.
BFD represents it by an absolute symbol with the value 0.  The fact that a
relocation against the undefined symbol is shown in this way may be
confusing, but I don't think there is anything wrong with it.  The symbol
with the empty name has nothing to do with this filename symbol, which
just happens to have the same value, but has a different (non-empty) name.
