Failure to compile //examples:beginner_cc on Apple Silicone MacOS

[ariellubonja]

Hi Team!

Using the latest main changes, with bazel build --config=macos --cxxopt=-std=c++17 "//examples:beginner_cc"

I get error: expected identifier or '('. Adding or removing --cxxopt=-std=c++17 does not affect the result. Am I doing something wrong?
