* Use GCC 4.3 by default.

* Updated stdenv-linux:

  - The bootstrap tools are no longer statically linked (except for
    binaries in the Nixpkgs tree used to download and unpack the
    bootstrap tools).

  - x86_64 uses the same static binaries as i686.  This makes the
    Nixpkgs tree a bit smaller.

  - Use the Linux 2.6.28 headers.
