Lluís Batlle i Rossell 7ade207f6b - Removed all *NoCross expressions I dupilcated in nixpkgs, while maintaining
the cross compilation functionality.
- I renamed some expected stdenv.mkDerivation parameter attributes so we can
  keep this branch properly updated from trunk. We agreed with Nicolas Pierron
  doing a massive renaming, so all current buildInputs become hostInputs (input
  as build for the host machine, in autotools terminology) , and
  then buildInputs would mean "input as for the build machine".
  By now, the specific "input as for the build machine" is specified through
  buildNativeInputs. We should fix this in the merge to trunk.
- I made the generic stdenv understand the buildNativeInputs, otherwise if
  we start changing nixpkgs expressions so they distinguish the current
  buildInputs into buildInputs and buildNativeInputs, we could break even more
  nixpkgs for other platforms.
- I changed the default result of mkDerivation so it becomes the derivation for
  to be run in the build machine. This allows, without any special rewriting,
  "fetchurl" derivations to be always results for the build machine to use
  them.
- The change above implies that, for anyone wanting to cross-compile, has to
  build the hostDrv of the wanted derivation. For example, after this commit,
  the usual test of "nix-build -A bison.hostDrv arm.nix" works. I described
  the contents of this arm.nix in r18398.

Lluís Batlle i Rossell 8c638e5e68 Fixing what I broke in the last commit in setup.sh.
I made the stdenvCross adapter simpler, according to Nicolas Pierron comments,
and I commented it a bit.

There are still jobs to do. At least:
- Plan for the general renaming from buildInputs to hostInputs
  - We should not break merges from trunk.
- Make the generic stdenv understand about host/buildInputs, at least for
  native builds, because it is used in the always-native building of
  stdenvLinux. This should allow us to remove all duplications of "*NoCross" in
  nixpkgs.

Lluís Batlle i Rossell e7c8e8da4f I made the whole nixpkgs dependencies available to the cross compiler, no
needing to keep a new tree of expressions apart for the expressions to get
cross-compiled.

I changed the whole way of using cross compilation with nixpkgs, which before
was done through a simple adapter.

Now the adapter became complex, and I've tried to avoid the most obvious
recursivities. For example, the fetchurl expression should
never be cross-compiled, as the gmp, mpfr, and some others, like
some ncurses, perl, ... I made overrided copies of those necessary as
perlNoCross, ncursesNoCross, as stdenvNoCross, keeping in mind that
the stdenv (capable of cross compilation) is built upon stdenvNoCross using
an adapter.

So, to cross compile, instead of building using "nixpkgs/default.nix",
you should build with your
own "myarchiteture.nix", which should have contents like these, for example:

import /etc/nixos/nixpkgs/default.nix
{
    crossSystem = {
        config = "armv5tel-unknown-linux-gnueabi";
        bigEndian = false;
        arch = "arm";
        float = "soft";
    };
}
