Both i386 and x86_64 architectures are supported by the arch/x86
directory in the kernel. So, when we copy the kernel configuration
file to arch/$(KERNEL_ARCH)/configs/, it does not work because
arch/i386 and arch/x86_64 do not exist.
So, we introduce KERNEL_ARCH_PATH, which is the path to the
architecture specific directory in the kernel source tree.

add support for it.

* renamed sh4_defconfig to qemu_sh4_r2d_defconfig, for consistency
with other Qemu platforms supported
* renamed board/qemu/sh4 to board/qemu/sh4-r2d
* minor fixes in the readme.txt
* remove useless statements in the minimal defconfig
* switch to a fixed kernel version instead of "same as headers"

The kernel being a component that often needs a fairly important set
of changes to be adapted to a particular hardware platform, having
maximum flexibility on the patching process is a nice
thing. Therefore, as per the discussions from the Buildroot Developer
Day, we add a mechanism to apply a list of patches (that could come
either from URLs, local files or local directories).

Now that minimal kernel defconfigs are used in Buildroot, the problem
is that copying those minimal configuration files to .config in the
kernel source tree does not work, as kconfig will ask interactively
what should be the value for all unspecified options.
On suggestion on Sam Ravnborg, the easiest way to solve this is to
import the minimal defconfig file as a defconfig inside the kernel
tree (in arch/$(ARCH)/configs) and configure the kernel with it.

Those folders are currently created using makedevs according to the
specifications in device_table.txt. However, as makedevs is no longer
executed when dynamic device creation methods are selected (devtmpfs,
udev, mdev), those folders must be created differently. We choose to
put them directly into the default filesystem skeleton.

Paul Jones documented at
http://pauljones.id.au/blog/2010/07/using-buildroot-on-a-mini2440/ how
to use Buildroot to generate a system for the FriendlyARM Mini2440
platform. This patch integrates Paul's work into Buildroot.
Unfortunately, the kernel being 2.6.32, we can't easily use a minimal
defconfig here. The mini2440 support has been merged into more recent
kernels, but I don't have the hardware to test.

It was supposed to be the support for AT91SAM9260 using a parallel flash
(instead of the usual dataflash). But the provided U-Boot configuration
at91sam9260pf.h was not used anywhere, and it was unsufficient to add
correct support in U-Boot (some changes in U-Boot Makefile would also be
needed). Additionnally, this configuration has not been merged into U-Boot
upstream since 2007 (when it was added to Buildroot).
Therefore, let's get rid of this configuration. If some users are
interested, we can re-introduce it properly with their help.

Minimize the board defconfig, remove custom busybox configuration,
custom kernel configuration (use the kernel defconfig instead), custom
device table and target skeleton. The only difference in the target
skeleton was the support of mdev and the usage of an automount
script. Instead of adding this in a board-specific way, we should
provide board-independent configuration options. There are already
patches contributed to add support for mdev.

Minimize atngw100_defconfig, remove atngw100-base_defconfig, and
remove the target skeleton and device table. Instead of having
complete copies of new target skeletons (making them hard to
maintain), we should just have a post-build script that
adds/removes/tweaks the existing target skeleton.
Moreover, most of the tweaks in this target skeleton were for specific
packages, but the policy now is that board defconfig should just build
a basic root filesystem with Busybox, and let the user select
whichever set of packages (s)he wants.

Those are not associated with any specific hardware system (PC or
another i386 system). Moreover, the fact that those configurations
require the build of a JFFS2 filesystem, very uncommon on PC systems,
seems to indicate that those configurations are not really being used
today.
It would make more sense to have a qemu_i388_defconfig (building a
kernel with just the device drivers for Qemu) and possibly a
pc_i386_defconfig (building a kernel with many device drivers, and a
bootloader such as Grub or Grub 2).
We also remove the corresponding kernel configuration files.
