feature/native-comp 15aa239: * Handle `comp-native-driver-options' both as file-local both as global

[Andrea Corallo]

branch: feature/native-comp
commit 15aa239ba058ef02544e5dfaf066bd985d9b2f4f
Author: Andrea Corallo <akrl@sdf.org>
Commit: Andrea Corallo <akrl@sdf.org>

    * Handle `comp-native-driver-options' both as file-local both as global
    
        * src/comp.c (add_driver_options): Throw an error if
        `comp-native-driver-options' is set globally but
        'gcc_jit_context_add_driver_option' is not available, ignore for
        the file-local case.
