Closes#2707
It's not only for kernel headers, and the kernel headers .mk file
isn't included for crosstool-ng toolchain, which broke linux/u-boot/..
builds.

Has been marked as broken for more than 1 year, with no indication
that anyone cares, and it needs a bunch of special handling.

Closes#751.
Make kernel headers snapshot more user friendly by making it more obvious
that it's about using a local kernel snapshot, and error out with a sensible
error message if the option is enabled but no linux-2.6.tar.bz2 is present
in DL_DIR, rather than trying to fetch it from kernel.org.
Furthermore fix the bug where it tried to use linux-2.6..tar.bz2 instead of
linux-2.6.tar.bz2.

To reflect the new output directory hierachy rename the Makefile variable
TOOL_BUILD_DIR to TOOLCHAIN_DIR.

- arch/sh and arch/sh64 got merged in 2.6.25, so use arch/sh for sh64 as well
- use little endian for sh64, like for 32bit sh
sh64 still doesn't build, but gets further along now.
Split build of kernel headers and kernel image into two source trees.
Kernel headers are built in $(TOOL_BUILD_DIR)
Kernel build is in $(PROJECT_BUILD_DIR)
Make sure that kernel patches are applied to the kernel tree in
$(PROJECT_BUILD_DIR)
Add board specific patches, if available.
normalize the passed in ARCH, from the looks, so we have to normalize it manually. XXX: FIXME upstream via a simple shell script like the cc-checks!
FIXME: flesh this out..
LINUX_VERSION.
Use LINUX_HEADERS_VERSION instead of LINUX_VERSION as that variable is used
for the actual kernel version used which might be different than the headers
version.
E.G. LINUX_VERSION is set in the target/device/* files. If this version
doesn't match the selected kernel headers version the patches won't be applied.
buildroot, the header files will be re-extracted, but they will not be put in
exactly the right place if the name of the extracted directory includes the
kernel version numbers.
For example, linux-libc-headers-2.4.25.tar.bz2 will be extracted to
$(TOOLCHAIN_BUILD_DIR)/linux-libc-headers-2.4.25, and then the mv command will
move the newly extracted headers into the already existing
$(TOOLCHAIN_BUILD_DIR)/linux directory, instead of replacing that directory as
desired.
The fix is to first remove the $(TOOLCHAIN_BUILD_DIR)/linux directory and then
do the mv command.
