    giscanner: Recognize _Thread_local as a storage class specifier
    
    _Thread_local is a C11 keyword, and thread_local is a macro to make it
    more confortable to read. As this keyword can only be used in variable
    declarations, not in function return values or parameters, it cannot
    be included in bindable APIs and we can safely ignore it.
