The 'vmlinux' target in the linux build directory is a generic target. It may
not be directly bootable for all architectures, but for projects where a custom
bootloader is used, it can be of value.
Previously, this target was only available for mips architectures. This patch
removes this restriction.

The vmlinux kernel target is valid for powerpc kernels too.
In fact this broke the qemu sample config.

Bump default kernel vesion to 3.1 to match headers.
Also implement downloads for 3.x series kernels.

Add a kernel sub-menu (called "Linux Kernel Extensions"), which makes
possible to patch it or tweak the kernel build step.
* All linux/linux-ext-*.mk files will be read by the make process.
* The menu can be customized in "linux/Config.ext.in".

This is useful for ARCHes like PowerPC that have a whole lot of
special targets for each different board. The kernel image target
tells make which OpenFirmware machine description file is combined into
the kernel binary.

The ELF vmlinux image found at the root of the kernel source tree is
the format that Qemu needs when emulating mips(el) or ppc targets, so
add support for it.

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).

Some Linux kernel output image formats are available on some archs,
some not. For example 'uImage' is not supported on MIPS, so let's
prevent the user from making this selection.

This patch introduces a single, simple, infrastructure to build the
Linux kernel. The configuration is limited to :
* Kernel version: a fixed recent stable version, same as kernel
headers version (for internal toolchains only), custom stable
version, or custom tarball URL
* Kernel patch: either a local file, directory or an URL
* Kernel configuration: either the name of a defconfig or the
location of a custom configuration file
* Kernel image: either uImage, bzImage, zImage or vmlinux.
