Work it around by overriding the built-in feature-check macro used by the

detects macOS, but fails to set the macro's old name `TARGET_OS_OSX`, then
continues to set it to a default value of 0. Other parts of the SDK still
rely on the old name, and with this inconsistency our builds fail due to
missing declarations. It happens when using mainline llvm older than v18.
Later versions fixed it by predefining these target macros, avoiding the
faulty dynamic detection. gcc is not affected (for now) because it lacks
the necessary dynamic detection features, so the SDK falls back to
a codepath that sets both the old and new macro to 1. */
