### Description / Steps to reproduce the issue
## Description / Steps to reproduce the issue
While testing the Zig `hello_zig` example on `sim:x86_64`, I found that it
cannot be built with Zig 0.13.0 due to two build issues.
### Steps to reproduce
1. Configure NuttX for `sim:x86_64`.
2. Enable the Zig hello example:
```
CONFIG_EXAMPLES_HELLO_ZIG=y
```
3. Build NuttX.
The build first fails because `tools/Zig.defs` generates the following
target:
```text
-target x86_64-freestanding-sysv
```
However, Zig reports:
```text
error: unknown ABI: 'sysv'
```
After locally changing the target to a Zig-supported ABI, the build proceeds
further but then fails during linking with:
```text
undefined reference to `__zig_probe_stack'
```
The generated Zig object references `__zig_probe_stack`, but the required
compiler runtime is not linked.
After applying local changes, the project builds successfully and the
example runs correctly:
```text
NuttShell (NSH)
nsh> hello_zig
[sim]: Hello, Zig!
```
At this point I'm unsure what the preferred upstream approach is for
addressing these two build issues, so I'm opening this issue first before
preparing a patch.
