This toolchain contains Mach-O binaries and might not be useful in the
first place, but there are programs like dsymutil, where Apple didn't
release the source code, so we need a Mach-O loader...

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?

We're already using tzcode inside tzdata, so let's make it available as
an output here. The reason we need it is in order to compile OpenCFLite.

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 basically is binutils for Mac OS X, but ported to work on
(GNU/)Linux and FreeBSD.
And it's up-to-date as well! I'm mentioning this, because it was quite
hard to find a recent port of it and I just accidentally stumbled on it
while trying to do the port by myself.
So thanks to @tpoechtrager for doing this.
Also, I've added two more patches, which essentially are:
* ld-rpath-nonfinal:
This allows -rpath to be used for linking non-final builds, which
was allowed for earlier versions of cctools and got a check for
that in more recent versions.
* ld-ignore-rpath-link:
Ignores the -rpath-link option, because the cross-wrapper uses it
in different places. Unfortunately, the cctools linker doesn't
support it, so we might need to implement this later if it's
possible (I'm not a Mach-O man^H^H^Hexpert).

This package provides the SDK and standard library needed for
cross-compiling to Mac US X. We're using xpwn here to extract the DMG.
Also, this version (XCode 5.0.2) only contains the SDKs for version 10.9
and 10.8, so we might need to add requireFile directives for older
versions as well.

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.

So far, we determined this based on stdenv.is64bit, but there are cases
where you want to run/build a 32bit program on a 64 bit Windows.
This is now possible, by passing windowsImage.arch = "i686" | "x86_64"
to runInWindowsVM. Based an what was passed, the corresponding Cygwin
packages and setup.exe are bootstrapped.

Another very annoying part. Unfortunately, the only option we might have
here is to include it in nixpkgs or maybe make a fixed Hash on the
result of the closure fetcher.

As the official Cygwin setup binary download doesn't come in snapshots
or even versioned, the fetchurl of setup.exe will frequently fail, which
in turn will annoy us as hell (or at least me).
One warning though: The fetchurl is currently broken and the cross-build
might not work yet for example on mingw32 (mingw-w64 branch on its way),
but the upstream URL has already changed and the new version contains a
bug (not yet tracked down) which breaks our Windows bootstrap process.
So to conclude: If it's already broken, make it at least "less broken".
"Not broken" is coming soon with the merge of the mingw-w64 branch.

This is primarily going to be used for vmTools.runInWindowsVM, but in
theory, it could also work with Nix on CygWin which I haven't tested.

Coincidentally, even with this typo, most tests work anyway, so I didn't
notice it in the first place.
