Custom dts files are still conditionally copied based on non existing
boolean. So it is currently not possible to use custom dts file(s) at all.
List of dts files is now iterated and files are copied into dedicated kernel arch dir.

Just use whatever the user specified in the list. An empty list means no
DTS was specified.
No need to add legacy option, as the behaviour does not change.

Some Linux kernel configuration options (such as CONFIG_UNWINDER_ORC)
require building a host program that needs libelf.
Users who have libelf installed on their system won't see a problem,
but users who don't have libelf installed will get a build
failure. Therefore, this commit adds an option that allows a user to
indicate that his Linux kernel configuration requires libelf. When
this option is enabled, we add host-elfutils to the dependencies of
the linux package (host-elfutils provides the libelf library).

Some Linux kernel configuration options (such as
CONFIG_SYSTEM_TRUSTED_KEYRING) require building a host program called
extract-cert, which itself needs OpenSSL.
Users having OpenSSL installed on their system won't see a problem,
but users who don't have OpenSSL installed will get a build
failure. This commit adds a new option that allows users to indicate
that their Linux configuration requires building host-openssl.

We were passing HOSTCFLAGS="$(HOSTCFLAGS)" to Linux. However:
- HOSTCFLAGS in Buildroot doesn't exist, and is empty, so this
assignment never did anything. The name of the variable in
Buildroot in HOST_CFLAGS.
- HOSTCFLAGS in Linux isn't used everywhere, and passing it overrides
the default HOSTCFLAGS value defined in the main Linux kernel
Makefile.
In addition, there is no way to pass additional host LDFLAGS in the
Linux kernel build system.
Therefore, we simply shoehorn our HOST_CFLAGS and HOST_LDFLAGS while
passing HOSTCC to the Linux kernel build system. This has been tested
to work fine with host OpenSSL and host libelf only available in
$(HOST_DIR).

For some boards, for example the Raspberry Pi, it's necessary to build
in-tree dts files as well as custom/out of tree dts-files (dt-blob.bin).
The existing logic made these two options exclusive, this commit changes
that to allow both in-tree as well as custom sources for dts files.

Currently, the rule to rebuild the Linux kernel with an initramfs
directly depends on the path of the file of the intermediate cpio image.
This is inherently "bad" from a purity point of view; linux.mk should
not have to delve into the fs internals.
Rather, make it directly depend on the "frontal" rule that generates the
cpio image.
Drop the comment for linux-rebuild-with-initramfs, it was misleading
(talking about generating "the initramfs list of files", which is not
what was done, since we use a cpio as source of initramfs, not a list of
files).

The LINUX_KCONFIG_FIXUP_CMDS are meant to deselect any compression
option that are not selected in the buildroot configuration. But it only
deselects the last one in the list instead of all of them because it
overwrites the LINUX_COMPRESSION_OPT_ variable instead of appending to
it. Only the last option set to that variable gets deselected.
This produces the warning:
.config:2216:warning: override: KERNEL_GZIP changes choice state
is emitted when buildroot runs olddefconfig when buildroot configures a
kernel with a custom config that has a different kernel compression
option set to what is configured in buildroot.
Accumulate all the deselected compression options instead of overwriting
them to ensure all non-selected options get deselected..

We don't have a hash for any linux version. We currently also don't
have a hash for the latest version, but if we ever add a hash, it
will only be for the latest version.
This simplifies the code a little because soon we will add hash checks
for git as well, so we also need an exclusion in that case. It's much
easier to always exclude except in the single case where we do have a
hash.
