All tutorial exercises and examples that currently use `export_executable_symbols` will now need `EXPORT_SYMBOLS`. The example/tutorial tests are off by default and Darwin exports symbols by default so we may not see any immediate bot failures, but the tests will fail on Linux where symbols are not exported by default.
