Zig build on NuttX

[kassane]

Zig is a general-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.

Summary

I made an example of hello_zig in reference to the rust example accepted earlier.

Zig besides building from the language itself is also currently a clang wrapper (allow cross-compilation) allowing you to compile C and C++(libc++ only) projects.

Impact

none.

Testing

Arch Linux - simulation (latest version 0.9.x & master/nightly)

Rebase?

yes, please:
git remote add apache [email protected]:apache/incubator-nuttx.git

git fetch apache
git rebase apache/master
git rebase --interactive HEAD~9
[adjust your patchset in editor]
git push -f origin zig-build

[xiaoxiang781216]

@kassane I think the change for docker is also needed, you can create another patch for docker.

[xiaoxiang781216]

@kassane please merge the fix for the previous patch into one. We need ensure each patch in the final shape.

[pkarashchenko]

Please squash intermediate commits. Other parts LGTM

There are some troubles with boards/sim/sim/sim/configs/zig/defconfig. Please regenerate it.

@kassane you can run "./tools/refresh.sh --silent sim:zig" to normalize defconfig.

Look like the CI doesn't get the last change from apps git, let retrigger CI again.

[kassane]

I found some errors in app rules:

• Zig: Application.mk fix nuttx-apps#1080

[pkarashchenko]

@kassane please rework the changes and issue the PR again.

@kassane please rework the changes and issue the PR again.

OK. I'm working on it! After solving the problem, the new PR will be requested.

Status

• Actually, on yesterday I had done a manual test, after building libapps with zig hello_example and it worked.
  But during build systems, I realized that zig was not invoked by Application.mk, although in the test also enabled rust_example (ref) and it was invoked normally.
