c8ef91fdb7 cmake: llvm: Use '=' for --config to improve compatibility
Replaces space with an equal sign when assigning the clang configuration
file to the --config parameter. This change improves compatibility with
tools that parse the compilation database and expect compiler arguments
to be separated by space.

f2c8a5acc4 cmake: linker: ld: Use "-Map <mapfile>" for legacy compatibility
The build system currently generates mapfiles by invoking ld with the
"-Map=<mapfile>" command line argument. This variant of the flag was
introduced in GNU binutils 2.20.

To enable compatibility with legacy versions of the GNU ld, the argument
has been replaced with the "-Map <mapfile>" variant.

3c97bf1014 cmake: kconfig: regenerate .config when Kconfig sources are updated
The existing logic caused a regeneration when any of the .conf files
changed, but modifying the Kconfig files can also cause the .config file
to become out of date e.g. by adding a new config option or by changing
the default value of a config option (when that default is not
overridden by a .conf).

Without this change, an incremental build wouldn't pick up the new value
and would require the user to notice that and manually do a clean build.

146e22fca4 cmake: xcc/xt-clang: fix for proper system include paths
Although xt-clang is based on clang, for some reason, it still
lists xcc system include path as the first search path (e.g.
for stddef.h), and the clang system include path as last. This
creates a big issue when the code starts to use any standards
past C89 (since xcc is based on GCC 4.2). We can use compiler
property nostdin_include to add -isystem to compiler options.
However, some modules (e.g. picolibcs) somehow ignore this.
So we also need to forcibly do add_compile_options() to make
sure the clang system include path is placed before the xcc
system include path.

d5fc087690 cmake: Fix warning if a Zephyr library is created in app-mode
zephyr_append_cmake_library attempts to warn the user if a user calls it
to create a Zephyr library while the build is in application mode. At
that stage of the build, the list of Zephyr libraries has already been
processed so the function is effectively a no-op.

This heuristic used to determine if the build was in kernel mode or
application mode checked for the presence of the zephyr_prebuilt target.
This check was broken by a previous commit that renamed this target.

This commit fixes the heuristic by checking for the zephyr_pre0 target.

This was tested by calling zephyr_append_cmake_library from some
application build files, building the application, and seeing the
warning only for the call I added. No warnings were printed for any
Zephyr internal libraries.

b6766aeb6b cmake: compiler: Remove -fshort-enums
"-fshort-enums" changes the ABI. It's not enabled for gcc, so it's not
clear why it's enabled for clang (only ARM) and armclang, other than it
looks like some users of these toolchains may be linking against code

As an example, when compiling with clang, CONFIG_LTO, and a toolchain
built without "-fshort-enums", the linker warns:

ld.lld: error: linking module flags 'min_enum_size': IDs have

bb797ab421 cmake: Fix compilation options for kobject_hash*.c
Rework how the compilation-options for the gperf generated
kobject_hash*.c files are put together to fix problems with SHELL:

zephyr_get_compile_options_for_lang_as_string() returns the set of
options as a cmake generator expression string which is cumbersome to
edit. This caused the command line for the IAR toolchain to have broken
SHELL: entries, and other some command line entries being postfixed by
"gnu".

This also adds CMake compiler properties for no_function_sections and
no_data_sections options

da197fe9ef sysbuild: Import image devicetrees
Make the image devicetrees available to sysbuild for advanced use cases.

This is done by calling `zephyr_dt_import` on each image target. The DT
target properties are all expected to be prefixed with `DT_`, so there
should be no conflicts.

Thus, the DT contents of a given `<image>` can be retrieved using e.g.:

    dt_nodelabel(<var> NODELABEL <label> TARGET <image>)

as noted in `extensions.cmake`.

7cddb2a5e5 cmake: extensions: Add TARGET arguments to the dt_* API
The CMake dt_* API is backed by target properties. By default, it uses
the target named `devicetree_target` that is initialized in `dts.cmake`.

We should be able to customize this, now that we have a function for
loading those properties into a different target. For example:

    zephyr_dt_import(EDT_PICKLE_FILE /path/to/edt.pickle TARGET target)

    dt_nodelabel(node NODELABEL label TARGET target)

This would make it possible to reference multiple devicetrees in the
same build system, particularly sysbuild.
