This sets 5.0 to be the default, moving from 4.19 which was used instead
of 4.20 for the LTS branch.
We need to update linux/linux.hash as part of this commit, because
package/linux-headers/linux-headers.hash is a symlink to
linux/linux.hash.

4.20.x is not a long term support kernel, but 4.19.x is (supported until end
2020):
https://www.kernel.org/category/releases.html
With the upcoming Buildroot 2019.02 release being a LTS release, default to
4.19.x instead.
Notice: The userspace API breakage in net_stamp.h causing build failures has
now been fixed in 4.19.14 by commit e4a2ffe9029fd (net: Use
__kernel_clockid_t in uapi net_stamp.h)

to 4.20+.]

According to https://www.kernel.org/category/releases.html, these kernel
versions are no longer supported, so drop them now that we have added 4.20.x

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But since 4.17 is no longer maintained, the proper fix is to really drop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.

These versions received their last updated more than three months ago
and are no longer supported according to

legacy entries.
