This change enables specific compiler and linker options to be used in
the case that an arch/posix/os.arch.cmake file exists.
Note: os and arch in the above case are evaluations of
CMAKE_HOST_SYSTEM_NAME and CMAKE_HOST_SYSTEM_PROCESSOR.
Otherwise, the existing "generic" compiler and linker flags in
arch/posix/CMakeLists.txt are used.
Additional flags and checks are provided in
arch/posix/Linux.aarch64.cmake.
Added scripts/user_wordsize.py to detect if userspace is 64-bit or
32-bit, which should be consistent with the value of CONFIG_64BIT
for Aarch64 on Linux.
Fixes#24842

For some reason, some users have been facing a bizarre issue
in which the -m32 option was not being passed to the linker
by cmake when building for the POSIX arch as a 32bit target,
even though the option was actually supported.
Instead of using zephyr_ld_options() which checks if an
option is supported and drops it otherwise, use
zephyr_link_libraries()

We need to pass -m64 instead of -m32 when CONFIG_64BIT is set.
This is pretty x86 centric. Many platforms don't have the ability
to select between 32-bits or 64-bits builds and either of those should
be dropped in that case with restriction on the available configuration
done elsewhere. But for the time being this allows for testing both.

Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.
By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

This adds a compiler option -fno-inline for code coverage on
architectures which supports doing code coverage. This also
modifies the ALWAYS_INLINE macro to not do any inlining. This
needs to be done so code coverage can count the number of
executions to the correct lines.

LTO is not supported yet, but there are a handful of references to the
flag '-flto' and the non-existent Kconfig option 'LTO'. To not confuse
users about whether LTO is supported or not, we should remove this
dead code.
As an aside, prototyping has shown that supporting LTO will give
signicant (10%) code size improvments, but will not be trivial to
support due to how we process object files with python.

Remove having ${BOARD_DIR} in the global include path for Zephyr builds.
Needed to add this to the arch/posix because of how posix "boards"
define various things like interrupt handling.

Initially missing function prototypes warnings and undefined macro
warnings were disabled to quickly prototype the posix arch and
native_posix board.
But there is no excuse anymore to have this warnings disabled.

The native_posix random driver uses random() and srandom()
whicha are old XOPEN POSIX extension (part of POSIX 2001).
To avoid compiler warnings due to the host libC headers
not including this prototypes otherwise, let's define
this 2 macros.

Address Sanitizer helps finding issues related to memory: buffer
overflows, usage of uninitialized memory, etc. This is available in
both Clang and GCC for a while, and, since the POSIX port is only
meant for testing, this will help find issues.

Both variables were used (with the same value) interchangeably
throughout CMake files and per the discussion in GH issue,
ZEPHYR_BASE is preferred.
Also add a comment with explanation of one vs. the other.

Modify the linker script with the command INSERT.
It instructs the linker to augment the default linker script
SECTIONS with the ones provided with the one provided in

It also modified the meaning of the -T switch, so it no longer

switching
A new soc for it (inf_clock) which emulates a CPU running at an
