The function ‘mkDerivation’ now checks whether the current platform
type is included in a package's meta.platform field. If not, it
throws an exception:
$ nix-build -A linux --argstr system x86_64-darwin
error: user-thrown exception: the package ‘linux-3.10.15’ is not supported on ‘x86_64-darwin’
These packages also no longer show up in ‘nix-env -qa’ output. This
means, for instance, that the number of packages shown on
x86_64-freebsd has dropped from 9268 to 4764.
Since meta.platforms was also used to prevent Hydra from building some
packages, there now is a new attribute meta.hydraPlatforms listing the
platforms on which Hydra should build the package (which defaults to
meta.platforms).
First, pass in `self' again so that overriding works properly (thanks
for pointing that out, @edolstra)
Second, instead of having linuxPackages*.kernel mean something different
inside the set and out, add a new attribute linuxPackages*.kernelDev,
which for the generic kernel is simply linuxPackages*.kernel but for the
manual-config kernel is the `dev' output (which has the build tree,
source tree, etc.)
The second change required trivial modifications in a bunch of
expressions, I verified that all of the linuxPackages* sets defined in
all-packages.nix have the same drv paths before and after the change.

I'm not entirely sure what the appropriate license attribute for this
package is. The license [1] says:
| 2.1.2 Linux/FreeBSD Exception. Notwithstanding the foregoing terms of
| Section 2.1.1, SOFTWARE designed exclusively for use on the Linux or
| FreeBSD operating systems, or other operating systems derived from
| the source code to these operating systems, may be copied and
| redistributed, provided that the binary files thereof are not
| modified in any way (except for unzipping of compressed files).
It sounds to me like this gives NixOS the right to re-distribute the
files (because we don't modify them). The 'proprietary' license sort-of
fits that. On the other hand, we seem to assume that proprietary
software cannot be redistributed, which doesn't apply here.

Several libs from the Nvidia distribution was not
copied to the nix store during installation. Therefore,
OpenCL was not working, for example.
The various nvidia-legacy packages are probably also
missing libs, this commit does not touch them, though.
