gcc-2.95: Remove

Hasn't built in a long time.
gcc-4.1: Remove

No longer used and doesn't build.
util-linux: Update to 2.22.2

This update is essential because coreutils no longer provides ‘su’.
Also enable ‘last’ and some other commands so that we can get rid of
sysvtools.
gcc-upc: Remove

This version (4.0) is obsolete.  And UPC will be merged in GCC 4.8
anyway.
eject: Remove

This command is part of util-linux now.

Fixing the kernel target for raspberrypi (zImage)

Removing uboot things about it too.
raspberrypi platform: adding a missing uboot attr

It's required, even if set to null, along all nixpkgs.
Update the raspberry pi kernel to one newer.
git: adding an option not to build the manual

asciidoc+xsltproc take hours to run
Raspberrypi platform: make ext4 in kernel

I also make other modules in-kernel. I originally copied this
from the sheevaplug kernel, but the sheevaplug runs the initrd
and the raspberrypi not.
Adding an automatic proper platform for some systems we know

That eases the burden of having to always set the platform at
least in the non-pc pure nixpkgs platforms.
stdenv bootstrap: removing xz override from stdenvLinuxBoot4

Due to xz being override in the last stdenv and also in the previous, the
nixpkgs xz ended up being built by bootstrap-tools, and thus depending on it
through libgcc_so.so.1. That ends up making 'nix' with a runtime
dependency on bootstrap-tools.
