The `platform` field is pointless nesting: it's just stuff that happens
to be defined together, and that should be an implementation detail.
This instead makes `linux-kernel` and `gcc` top level fields in platform
configs. They join `rustc` there [all are optional], which was put there
and not in `platform` in anticipation of a change like this.
`linux-kernel.arch` in particular also becomes `linuxArch`, to match the
other `*Arch`es.
The next step after is this to combine the *specific* machines from
`lib.systems.platforms` with `lib.systems.examples`, keeping just the
"multiplatform" ones for defaulting.
I hate the thing too even though I made it, and rather just get rid of
it. But we can't do that yet. In the meantime, this brings us more
inline with autoconf and will make it slightly easier for me to write a
pkg-config wrapper, which we need.
While it is easy to make a custom kernel by applying kernelPatches it is
not so easy to get the corresponding headers; the derivation uses a
hard-coded kernel version.
This makes us less reliant on the systems/examples.nix. You should be
able to cross compile with just your triple:
$ nix build --arg crossSystem '{ config = "armv6l-unknown-linux-gnueabi"; }' stdenv
Carefully fake cc-version and cc-fullversion to avoid needing a compiler
for the kernel itself to build the headers.
For some reason, doing `make install_headers` twice, first without
INSTALL_HDR_PATH=$out then with, is neccessary to get this to work.
It's not actually needed, and AFAICT has never been. Or at least
Buildroot can build kernel headers as old as 3.2 without running the
config phase.
While at it, set ARCH unconditionally.
Extracting headers from a grsecurity patched kernel triggers additional
build steps that require gcc plugins. For this to work, we'd need to
add gmp, libmpfr, and libmpc to the build inputs as well as run `make
prepare` before installing the headers (lest the build fail due to
missing files).
Out-of-tree modules use kernel.dev and user space should use the Linux
API headers used to build libc, not headers extracted from random
kernels, so fixing this for grsecurity is pointless.
This reverts commit b0adde8f8a5f22cf45f32df64bba149f326dec85.
Doesn't fix the issue for grsec kernels.

In most cases, this just meant changing kernelDev (now removed from
linuxPackagesFor) to kernel.dev. Some packages needed more work (though
whether that was because of my changes or because they were already
broken, I'm not sure). Specifics:
* psmouse-alps builds on 3.4 but not 3.10, as noted in the comments that
were already there
* blcr builds on 3.4 but not 3.10, as noted in comments that were
already there
* open-iscsi, ati-drivers, wis-go7007, and openafsClient don't build on
3.4 or 3.10 on this branch or on master, so they're marked broken
* A version-specific kernelHeaders package was added
The following packages were removed:
* atheros/madwifi is superceded by official ath*k modules
* aufs is no longer used by any of our kernels
* broadcom-sta v6 (which was already packaged) replaces broadcom-sta
* exmap has not been updated since 2011 and doesn't build
* iscis-target has not been updated since 2010 and doesn't build
* iwlwifi is part of mainline now and doesn't build
* nivida-x11-legacy-96 hasn't been updated since 2008 and doesn't build
Everything not specifically mentioned above builds successfully on 3.10.
I haven't yet tested on 3.4, but will before opening a pull request.

some redundant builds (e.g., GMP was built three times).
* Updated GMP to 5.0.2.
* Updated PPL to 0.11.2.
* Remove ad hoc flags to build GCC's dependencies statically.
Instead, use the ‘makeStaticLibraries’ stdenv adapter.
* Build GMP with C++ support by default.

‘linuxPackages.kernel’, because then every minor kernel upgrade will
cause a rebuild of everything. So fix it at 2.6.35.
