native_simulator: include folder for missing <asm/errno.h>

[cfriedt]

On an x86_64 Ubuntu host, the following command would result in an error.

west build -p -b native_sim/native tests/net/wifi/configs -T wifi.build.hostapd_ap ... In file included from /usr/include/bits/errno.h:26, from /usr/include/errno.h:28, from ~/zephyrproject/zephyr/scripts/native_simulator//common/src/nce.c:24: /usr/include/linux/errno.h:1:10: fatal error: asm/errno.h: No such file or directory 1 | #include <asm/errno.h> | ^~~~~~~~~~~~~ compilation terminated.

Include /usr/include/x86_64-linux-gnu in the search path so that the build succeeds.

Fixes #96566

This fixed the build on my local Ubuntu machine. Not sure if it's absolutely necessary in CI. Also, aarch64 might need a separate path.

There may be a more elegant way of determining the path, so I would be happy to make corrections.

If the path does not exist most compilers that I've worked with will not complain.

We don't usually hardcode system paths like this? Also, I am not building on x86_64, but aarch64.

#96582 (comment)

Please feel free to suggest something if there is a similar need on aarch64.

I'm also happy to use a more elaborate approach if there is one for getting the path.

Yes, this is wrong e.g. for openSUSE. And anyway looks like this needs another fix

This is wrong. I will look into the issue, but whatever it is, this is not the way to go

Thanks - it worked for me, but if there is a better way (or a way that you prefer), I'm happy to use that.

I think this was a user error - sudo apt install -y linux-libc-dev:i386 fixes it for me.
