    aarch64: Avoid std::string in static data
    
    Just a minor patch to avoid having to construct std::strings
    in static data.
    
    gcc/
            * common/config/aarch64/aarch64-common.cc (processor_name_to_arch)
            (arch_to_arch_name): Use const char * instead of std::string.
