maintains the same semantics as Kernel’s module build
and compatible with Kconfiglib implementation.
The problem of kconfiglib not being able to use tri-states is this:
linux is here torvalds/linux@6dd85ff
The module option is extracted from one of the triate three states into a MODULE keyword.
Kconfiglib supports the default implementation of module to be MODULE for compatibility with the linux kernel, and triate degenerates into bool two states

This adds out-of-tree usage guide of CMake for FLAT, PROTECTED and KERNEL
configs so that more kernel developers can enjoy cmake for their daily

Current `CONFIG_PAGING` refers to an experimental implementation
to enable embedded MCUs with some limited RAM space to execute
large programs from some non-random access media.
On-demand paging should be implemented for the kernel mode with
address environment implementation enabled.

I used
cd nuttx
cmake -B build -DBOARD_CONFIG=stm32f401rc-rs485:nsh -GNinja
to config
and when following the instruction in this official websites I found the
command to use cmake to build the target is wrong.
which is "cmake --build build -t menuconfig" also wrong the output dir
"build/nuttx".
and by the way, In my practice I find the bin file and elf file is not
in build/nuttx but in build/. So I changed these. But I'm not 100% sure
that my fix is right as I'm a beginner, but what I fix works fine in my
computer. This is my first PR to the public doc. My fix maybe totally
wrong as I am not get into the nuttx, just following the instruction and
encountered some mistakes.
thx for reviewing

Update the gcc compiler to 10.3-2021.10 to be able to compile the latest NuttX version
Fix for error:

did you mean '-std=gnu++2a'?

To solve the issue of carrying object files from previous builds,
Matias changed the archiving process to re-archive libapps.a on every compilation,
if libapps.a carries more object files, incremental compilation will waste too
many time in re-archiving, compared with the previous implement, this is a degradation
of the build system. Referring to mature engineering projects such as cmake, if there
is configuration or source file changed, the best solution should be to reconfigure
the environment.
Revert this PR to ensure the compilation speed during incremental compilation.

| Fix: ensure archive files do not carry object files from prior builds
|
| In some cases, when NuttX configuration changes and this makes the
| object list used to build one of the .a libraries change as well,
| since the command used to build it is "ar crs" and this simply appends
| the list of object files, the library could still include object
| files from prior builds. This commit modifies the ARCHIVE macro to
| erase the .a file if it already exists.
|
| Since in some cases this behavior was actually expected (object
| files from a subdirectory were appended to a library created one
| level above) I added a ARCHIVE_ADD which works as ARCHIVE did.
|
| This change should greatly improve behavior of building after
| configuration changes.

According to `Documentation/guides/gdbwithpython.rst` and GDB's
documentation, the `-ix` option "Execute commands from file `file`
before loading the inferior (but after loading gdbinit files)",
being the correct way of loading it to GDB.
A user reported me an issue while following our documentation
then looking his command line error I noticed the openocd stlink
interface was wrong: st-link-v2.cfg -> stlink-v2.cfg
wget is missing from some system (like macOS and Windows native),
it's better to use curl to simplify build environment.
