Using ALSA for non-Linux systems really doesn't make much sense, so
using buildNativeInputs to ensure it won't be used for cross-builds.
Of course, if you're cross-building to Linux, the dependency won't be
used, but right now we don't have a good way to easily check whether the
cross target is Linux.

Might be better to have something like stdenv.isDarwinTarget, which can
be used to test for native Darwin _and_ cross-built Darwin as a target.

This is just a minor fix, because when using "darwin64-x86_64-cc" for
config.openssl.system, the OpenSSL build scripts try to compile with
$prefix-cc, which is not available with the gcc-cross-wrapper.

The Makefile still contained calls to install with the -s (strip)
option, which we don't want because it uses the native strip utility and
we're going to crossStrip in fixupPhase later anyway.

The ld from cctools doesn't like the -soname argument, so let's strip it
off for now until we have a binutils <-> cctools bridge.

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.
