Cross-compiling stuff against Mac OS X's CoreFoundation won't work
without ObjC support, and we don't want to compile commandline utilities
only, right?

Let's finally hook everything into the existing cross-building
infrastructure. We're using --with-sysroot instead of --with-headers
here, because the XCode SDK contains references to /usr/lib.
I've tried to patch those references, but unfortunately (at least with
install_name_tool) it isn't possible to change those refernces in stub
dylibs.
So after bugging @tpoechtrager with annoying questions (thanks again), I
think my initial approach (patching the SDK itself and/or regenerating
the dylib stubs) was way to complicated so I ended up with this
implementation.
Also, I've added a condition to binutilsCross to use cctools if the libc
is set to libSystem. This might need some cleanups someday, mainly to
figure out how to properly bridge cctools and binutils.
So, as an example on how to cross-compile GNU Hello to Darwin, you can
use something like this:
(import <nixpkgs> {
crossSystem = {
config = "x86_64-apple-darwin13";
arch = "x86_64";
libc = "libSystem";
platform = {};
};
}).hello.crossDrv

This really hase some nice utilities for coping with HFS+ and DMG
format. We're going to use it for extracting the xcode DMG, but it could
be used for more, even generating DMGs.
The reason I'm using the fork instead of the repository from
@planetbeing is thet the fork contains a few fixes, especially for
dealing with symlinks in HFS+ images.
