Your ld needs to generate code compatible with an old ld.so. If that means
duplicating brokenness, it's unfortunately a requirement. The point of
getting a.out capability into binutils is to be able to produce binaries for
existing systems using GNU binutils.

Is that fixable? The assembler needs to cope, and produce code compatible
with an old ld.so too.
I'm pretty sure we're not the only binutils target that duplicates something
"broken" in the target's own native assembler and linker. :)
