Support GCC for unit test mode

[aleksisch]

Official documentation says:

GCC is not yet supported. Unittest mode should work but it's not yet tested.

Right now it fails to compile. GCC doesn't support the flag sanitize-coverage which is used inside fuzztest to disable (I guess) sanitizers in some internal directories.

I believe we should do any of this:

1. Report an error (or warning) for all cases with GCC like it was done here.
2. Skip this option in case of GCC (what I did in this PR).
   2.1 I don't know the reason behind this sanitize-coverage=0, maybe we can remove it.

Any chance this can be merged?

Thank you for the PR and thank you for your patience!

This "codelab" CI workflow is failing. It's because we pass the PR's branch name here to CMake over here, and it fails because that branch doesn't exist.
It doesn't exist because it's from your repo, so I guess we'd need to do with the repo the same as the branch over here.

Do you think you could fix this?

Yes! (we just need to make the CI green)

Hi. Thank you for your response. Could you explain how I can create a branch in the google/fuzztest repo? I didn't find a way to do it

No, what I meant was that I think we need to pass in github.repository similarly as we pass in github.ref_name here to CMake here.

Thanks!

@aleksisch, just wanted to check if you are planning to do this.

Yes, I'll investigate it

I hope this marks the start of decent GCC support ❤️
