I introduce the new nixpkgs parameter "platform", defaulting to "pc",
which was before defined as an attribute of nixpkgs.
I made the crossSystem nixpkgs attribute set parameter contain its own 'platform'.
This allows cross-building a kernel for a given crossSystem.platform in a non-PC
platform.
The actual native platform can be taken from stdenv.platform, and this way we also
avoid the constant passing of 'platform' to packages for platform-dependant builds
(kernel, initrd, ...).
I will update nixos accordingly to these changes, for non-PC platforms to work.
I think we are gaining on flexibility and clearness. I could cross build succesfully
an ultrasparc kernel and a mipsel kernel on PC. But since this change, I should be able
to do this also in non-PC.
Before this change, there was no possibility of distinguishing the "target platform" or
the "native build platform" when cross building, being the single "platform" attribute
always interpreted as target platform.
The platform is a quite relevant attribute set, as it determines the linuxHeaders used
(in the case, by now the only one supported, of linux targets).
The platform attributes are quite linux centric still. Let's hope for more generality to come.

This comes from:
svn diff ^/nixpkgs/trunk/@18255 ^/nixpkgs/branches/stdenv-updates/ > diff
patch -p0 < diff
and then adding into svn all files new from the patch.
trunk@18255 comes from the last time I updated stdenv-updates from trunk.

modules for the initial ramdisk if there were no additional kernel
module packages (such as the NVIDIA driver or AUFS), leading to a
kernel panic in the initrd. This was because in that case modprobe
would print paths referring to the kernel path rather than the
module aggregation path, and then `sed "s^$kernel^$out^"' would
silently fail. Fixed.
* Also, use depmod here rather than doing sed hackery on modules.dep.
* Also, `allowMissing' was broken (missing "$" before the variable
name).
