Some installations mount /tmp with the 'noexec' option, which prevents
running the program generated there to check the kernel headers.
Avoid the problem by generating the program under $(BUILD_DIR), passed
as the first argument to check-kernel-headers.sh.
We could globally export a TMPDIR environment variable with some path
under $(BUILD_DIR) but such solution would be too intrusive, depriving
the user from the freedom to set TMPDIR at his will (or needs).

When BR2_KERNEL_HEADERS_AS_KERNEL=y, we expect that the Linux kernel
headers code will be exactly the same as the Linux kernel code
itself. The code currently takes into account the patches defined by
BR2_LINUX_KERNEL_PATCH, but not the kernel patches that are stored in
linux's BR2_GLOBAL_PATCH_DIR.
So for example, the current qemu_riscv32_virt_defconfig has:
BR2_GLOBAL_PATCH_DIR="board/qemu/riscv32-virt/patches/"
With:
board/qemu/riscv32-virt/patches/
└── linux
└── 0001-Revert-riscv-Use-latest-system-call-ABI.patch
This patch gets properly applied when the Linux kernel is built, but
not when the linux-headers package is built.
This commit fixes that by making sure patches stored in the "linux"
BR2_GLOBAL_PATCH_DIR subdirectory are taken into account.

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.

With the arrival of linux v5.0, we need yet another condition to set
_SITE correctly. Instead of continuing this madness, solve the problem
generically: use v2.6 for 2.6.*, and use the number before the first dot
in the other cases.
While we're at it, remove the comment which has been incorrect since
80d7b68167 (7 years ago).

-rc kernels after v3.x are no longer available in the testing
subdirectory. Instead they should be fetched from cgit.
Commit ff4cccbdcf did this for linux
itself, now we also do it for linux-headers.
When fetched from cgit, .tar.xz can't be used. Adding this to the
existing condition is not so simple, so refactor how _SOURCE is set:
simply set it explicitly in each branch of the condition. While more
verbose (it is repeated 4 times), it's easier to understand and to
maintain.

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)

[Thomas: add comment in linux/Config.in and
package/linux-headers/Config.in.host so that we don't mistakenly bump
to 4.20+.]

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! ;-)
