arm_executor_runner is not an object file

[AIWintermuteAI]

🐛 Describe the bug

As a result of running
./run.sh --build_only --scratch-dir=build-dir on MacOS

cmake-out % size arm_executor_runner
__TEXT  __DATA  __OBJC  others  dec     hex
error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/size: file: arm_executor_runner is not an object file

Using arm-none-eabi-size instead works.

Thanks, good finding! Yes we should fix this :)
Do you want to make a patch and get some kudos? If not we can make one, no problem.

@zingo I can make a PR. But I was running this on Mac, which seems to be unsupported (?). Not sure if this issue is platform related, as in theory size on Linux x86 also would not work on ARM binary. But where was the person who wrote this cript running all of this, Linux on ARM machine?

I wrote this part of the script, and are using Linux on x86 I assume it could be that the size on my machine (and all testing machine used) "by-luck" can handle elf file for Arm as Linux version probably are happy as long as it's an elf file, so I missed that. It would be better to use the one from the embedded compiler e.g. I agree that arm-none-eabi-size is much better :) Sorry for the bug.

Even if MacOS is not supported I would like it to be in the future and fixing stuff along the way is nice. Thanks

Did a test on my maching replacing the 3 size with arm-none-eabi-size and it works perfectly fine in this setup, so it github PR testing is happy with the PR it should be fine :)
