Currently, the build fails when the kernel headers 4.17 are selected:
package/linux-headers/linux-headers.mk:149: *** LINUX_HEADERS_SITE
cannot be empty when LINUX_HEADERS_SOURCE is not. Stop.
This is caused by an hickup during the last merge of the next branch,
where the value for 4.17 got dropped from BR2_DEFAULT_KERNEL_HEADERS,
but the choice entry was left in.
The correct fix against that hickup would be to restore the 4.17 value.
But since 4.17 is no longer maintained, the proper fix is to really drop
4.17 altogether.
For good this time! ;-)

This enables a riscv64 system to be built with a Buildroot generated
toolchain (gcc >= 7.x, binutils >= 2.30, glibc only).
This configuration has been used to successfully build a qemu-bootable
riscv-linux-4.15 kernel (https://github.com/riscv/riscv-linux.git).

Add support for building toolchains against custom headers. Allows
the selection of a manual version, custom tarball or custom git
repository for the kernel headers. This enables toolchains to be
built against custom kernel headers without having to build a full
kernel.
This is particularly useful for new architectures, such as RISC-V
where updated kernel headers may not have made it into the mainline
kernel yet.

This commit reworks how linux-headers.mk is written to prepare adding
support for custom tarball/git fetching for the Linux kernel headers.
Basically, the idea is to have a single condition at the beginning of
the file that defines a number of LINUX_HADERS_* variables depending
on whether "kernel headers same as kernel" is used or not, and then
use these variables in the rest of the .mk file.

Added a hash file for the Linux kernel. Hashes have been copied
from the appropriate sha256sums.asc files on kernel.org.
The Linux hash file is also shared with the linux-headers package
via a symbolic link.

These versions received their last updated more than three months ago
and are no longer supported according to
https://www.kernel.org/category/releases.html, so drop them and add
legacy entries.

[Thomas: select an older kernel headers (4.9) rather than a newer one
