Commit 666084f494 ("linux:linux.mk: Add
"firmware-imx" dependency if needed") introduced a dependency from
linux to firmware-imx, but based on the incorrect BR2 option.
This commit fixes this mistake.

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.

gcc-12 is starting to trickle down to some distros, like Archlinux.
gcc-12 has new warnings, and detects more cases of issues, like new
UAF cases, which is causing build issues in code that was previously
building fine, as reported in #14826:
In file included from sigchain.c:3:
In function 'xrealloc',
inlined from 'sigchain_push.isra' at sigchain.c:26:2:
subcmd-util.h:56:23: error: pointer may be used after 'realloc' [-Werror=use-after-free]
56 | ret = realloc(ptr, size);
| ^~~~~~~~~~~~~~~~~~
subcmd-util.h:52:21: note: call to 'realloc' here
52 | void *ret = realloc(ptr, size);
| ^~~~~~~~~~~~~~~~~~
subcmd-util.h:58:31: error: pointer may be used after 'realloc' [-Werror=use-after-free]
58 | ret = realloc(ptr, 1);
| ^~~~~~~~~~~~~~~
subcmd-util.h:52:21: note: call to 'realloc' here
52 | void *ret = realloc(ptr, size);
| ^~~~~~~~~~~~~~~~~~
In that case, the kernel has already fixed their code, which is part of
5.17:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=52a9dab6d892763b2a8334a568bd4e2c1a6fde66
However, we can't easily carry that patch, because we don't know
whether the kernel the user uses already has the fix or not.
Instead, we can just tell the kernel to disable use of -Werror when
building host tools.
As a consequence, we can drop it from the perf-specific setting.
Fixes: #14826

The default defconfig target for the 64 bit powerpc kernel is
ppc64_defconfig, the big endian configuration.
When building for powerpc64le users want the little endian kernel as
they can't boot LE userspace on a BE kernel.
Fix up the defconfig used in this case. This will avoid the following
autobuilder failure:
VDSO32A arch/powerpc/kernel/vdso32/sigtramp.o
cc1: error: ‘-m32’ not supported in this configuratioin
make[4]: *** [arch/powerpc/kernel/vdso32/Makefile:49: arch/powerpc/kernel/vdso32/sigtramp.o] Error 1
http://autobuild.buildroot.net/results/dd76d53bab56470c0b83e296872d7bb90f9e8296/
Note that the failure indicates the toolchain is configured to disable
the 32 bit target, causing the kernel to fail when building the 32 bit
VDSO. This is only a problem on the BE kernel as the LE kernel disables
CONFIG_COMPAT, aka 32 bit userspace support, by default.

Since SDMA firmwares for imx[6,7,8] are now provided only by
firmware-imx package and not linux-firmware package [1]. If
CONFIG_EXTRA_FIRMWARE is set in the kernel config, the build will fail
if the imx firmware is not available.
