no need for it, the kernel build scripts already do their job

This commit provides Wi-Fi capabilities (CyberTAN chip) for the following devices:
- Kobo Mini (N705)
- Kobo Touch C (N905C) | Not yet tested but should work
- Kobo Glo (N613)

This step is handled in the root filesystem instead.

The former was done following this commit: https://github.com/torvalds/linux/commit/369842658a36bcea28ecb643ba4bdb53919330dd

Things *seem* to be going well!
The kernel sources were taken from Amazon's website at https://kindle.s3.amazonaws.com/Kindle_src_5.3.7.3_2715280002.tar.gz . When compiled and executed, it will display '2.6.35' as its version number, but it is in fact a 2.6.31 kernel. The reason for this hackery is that the glibc chroots in InkBox OS don't support 2.6.31 kernels, but do support 2.6.35.x ones. Changing the version number in the kernel Makefile seemed to do the job fine, and I haven't seen any problems in using glibc binaries and libraries, they all run fine with this new 'patch'.
This kernel has been slightly modified to support devtmpfs mounting via backporting and with some changes due to the 2.6.35 hack mentioned above, especially in the AR6003 Wi-Fi chip sources.
A new toolchain (arm-none-linux-gnueabi, GCC 4.4.1 from 2009) has been added in the toolchain/ directory and is the only toolchain I know that produces a bootable kernel.
You may compile a kernel for this device by executing the following command:

env GITDIR=/home/build/inkbox/kernel TOOLCHAINDIR=/home/build/inkbox/kernel/toolchain/gcc-4.4.1/ THREADS=8 TARGET=arm-none-linux-gnueabi scripts/build_kernel.sh kt root
