Concretely, there is an `ld`, and it runs at least enough to print out a usage 
note.

I can't say for certain *why* it works, though the way LLVM doesn't need a 
different binary for each target and the somewhat unusual way linking to libc 
and other system libraries works on Darwin. Though does a linker really need a 
libc? In principle, it could link things that don't link to libc, or even link 
libc itself.

I haven't tried actually linking anything with this package's `ld`, but, even 
if it turns out to not be fully functional yet, this is the package that 
contains Darwin's `ld`.

I did tweak the description in v2 to replace the reference to `libtool`, 
because Darwin's `libtool` is something completely unrelated than the program 
in the Guix package called `libtool`.
