Commit 0b9efc991f ("linux: use BR2_MAKE") switched LINUX_MAKE to
$(BR2_MAKE). However, this also implicitly sets LINUX_KCONFIG_MAKE.
Thus, when host-make is being used in a build that has
PER_PACKAGE_DIRECTORIES enabled, the dotconfig step will try to use the
make instance from the host directory, but since it is not listed in
LINUX_KCONFIG_DEPENDENCIES, it won't be available yet at that point in
time.
Add an explicit dependency to LINUX_KCONFIG_DEPENDENCIES to have it
copied over early enough.

Commit d06dca38bb (linux: cleanup

Remove the extra bracket to fix a syntax error in sed processing.

Commit d06dca38bb (linux: cleanup kconfig fixup processing) introduced
the conditional LINUX_KCONFIG_FIXUP_CMDS_ROOTFS_CPIO, using a negative
logic condition.
Switch that to use positive logic.

The following is an attempt o cleanup the output generated when fixing
up a Linux's Kconfig:
- Quiet the conditional check host-pahole to avoid having the message
used to describe a failure generate in the output in its script form.
- Move the initramfs fixups to their own conditional macros, and move
the comments out of the macro (mainly for developers managing the
implementation).
- Adding a generic "Updating kernel config..." message, to help inform
builders that the framework is actively processing Kconfig's (while
users may be pondering why the closing of a `linux-menuconfig` is
doing).

Since kernel version 6.2, the minimum GNU Make version is 3.82 [1]. We
have an optional host-make 4.0 minimum dependency, so we can use it as
is. It's a bit unfortunate that we have to apply this even to older
kernel versions, but make itself builds fairly fast compared to the
kernel.
Use BR2_MAKE and BR2_MAKE1 for linux, and depend on
BR2_MAKE_HOST_DEPENDENCY. In addition, we need to set LINUX_MAKE to
BR2_MAKE for use in the kconfig infrastructure.

A package might install headers that are incompatible with the kernel's
header. One example is the most recent version of pahole (1.24).
HOST_CC includes -I$(HOST_DIR)/include which comes before any include
logic the kernel might have thus forcing the kernel to prefer headers in
HOST_DIR.
The logic to substituting -I with -isystem is taken from
boot/uboot/uboot.mk.

This commit is based on earlier work from Łukasz Stelmach
<l.stelmach@samsung.com> to add support for different page sizes on
ARM64.
In his initial submission, Łukasz took an approach similar to this
one, i.e make it ARM64-specific. Following the feedback on the mailing
list, his second version [1] tried to generalize the logic to
configure the page size between architectures. But the general
consensus during the review process was that there wasn't much to
generalize in the end.
So, this new iteration is back to a simpler approach:
* We have new options in Config.in.arm to configure the page
size. Only 4 KB and 64 KB are supported, because our testing in
Qemu and real hardware has not allowed to get a successful setup
for 16 KB pages. We can always re-add support for 16 KB later if
that is resolved.
* The logic to define the ARCH_TOOLCHAIN_WRAPPER_OPTS options is
moved from the ARC-specific file to arch/arch.mk, and extended to
cover ARM64.
* The appropriate logic in uclibc.mk and linux.mk is added to tweak
the relevant configuration options.
* A test case is added in the runtime test infrastructure to test
building and booting under Qemu a 64 KB configuration, with all 3 C
libraries.
For the regular configuration of 4 KB pages, this commit makes one
functional change: on ARM64, -Wl,-z,max-page-size=4096 is now passed in
the compiler flags of the wrapper.

Buildroot documentation section 9.2.1.6 "Additional kernel extensions"
indicates support for kernel extensions defined in external buildroot
trees but unfortunately, there didn't seem to be any support in
br2-external script.
This patch copies 'init' code support to include external kernel
extensions defined in 'linux' dir at the br2-external root directory as
explained in documentation.
