This variable sets the minimal Mac OS X version required for
running binaries produced by the Darwin toolchain. Since it
defaults to the version of the user's SDK, setting it explicitly
should make our builds more deterministic. It's now set to 10.6
because that's what hydra.nixos.org runs.
Recent versions of Xcode don't install headers in /usr/include but
in a directory like
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include
So use that instead, falling back to /usr/include in case of an older
version of Xcode.
This allows various applications. It allows users to set global
optimisation flags, e.g.
stdenv.userHook = ''NIX_CFLAGS_COMPILE+=" -funroll-loops"'';
But the impetus is as an alternative to issue #229, allowing impure
stdenv setup for people who want to use distcc:
stdenv.userHook = "source /my/impure/setup-script.sh";
This is probably a bad idea, but at least now it's a bad idea in
people's configuration and not in Nixpkgs. :-)

I don't have i686-darwin to try this.

* Some fetchurl-related refactoring. The `realCurl' attribute is
gone, `curl' is the real thing. To prevent an infinite recursion in
`fetchurl' (because it depends on curl and building curl needs
fetchurl), curl and its dependencies (openssl, zlib, perl) use
`fetchurlBoot', which is the fetchurl used by the previous bootstrap
phase (e.g. the statically linked version of curl for
stdenv-linux). So as a result you can use https:// urls almost
everywhere.
There's also some hackery to prevent a different curl from being
built in every stdenv-linux bootstrap phase (namely the
stdenv.fetchurl attribute which allows fetchurl to be overriden
everywhere).

Glibc. This is useful when building GCC.
* gcc-wrapper: the dynamic linker has a different name on x86_64 and
powerpc.
* gcc-wrapper: "glibc" -> "libc", because someday we might support
different C libraries.
* gcc: don't do a multilib build (e.g., 32-bit support on x86_64),
don't need it.
* gcc: merge in support for static builds.
* gcc: various simplifications in the compiler/linker flags, hope they
work.

On the downside, the build process of stdenvLinux builds gcc 9 times
(3 x 3 bootstrap stages). That's a bit excessive.

* Make builders unexecutable by removing the hash-bang line and
execute permission.
* Convert calls to `derivation' to `mkDerivation'.
* Remove `system' and `stdenv' attributes from calls to
`mkDerivation'. These transformations were all done automatically,
so it is quite possible I broke stuff.
* Put the `mkDerivation' function in stdenv/generic.
