Add arm-gcc-bin@11

Add ARM 11.2-2022.02 toolchain

Should I also change the alias to point to the latest version?

[salkinium]

So maybe we need to skip this version, I get internal compiler errors when using it, which seems to be a known limitation? https://bugs.launchpad.net/gcc-arm-embedded/+bug/1970029

[salkinium]

Seems to be a bit of a disaster… https://developer.arm.com/Tools%20and%20Software/GNU%20Toolchain#Resources

thanks for the pr @salkinium!

maybe @fauxpark can fix this by compiling from source as he is doing for gcc@8 & gcc@9

[salkinium]

ARM released a new version without the compiler bugs: ARM 11.3-2022.08 toolchain.

[ladislas]

@salkinium could you update the PR? :)

[salkinium]

Sorry, I rebased the old commit by accident.

Do you want me to add a test block to satisfy the CI? Some simple main.c compilation to catch at least big internal compiler errors?

That would be great yes!

I think that something like this would be enough as we are using ARM binaries, we are not building anything ourselves.

I'm not familiar with ruby at all, so I'm poking in the dark about best practices etc. I also don't understand how to test the changes locally? Can you help me?

@salkinium the output of ...-gcc -v is a bit more verbose, so the assert was not working:

I replaced it with

  test do
    system "true"
  end

to make it simpler.

40 fixes this.

Ah, I was trying to use substring matching and failed. Your way is a simpler solution.
