    RISC-V: Fix mismatched new delete for unique_ptr
    
    gcc/ChangeLog:
    
            * config/riscv/riscv-target-attr.cc
            (riscv_target_attr_parser::parse_arch): Use char[] for
            std::unique_ptr to prevent mismatched new delete issue.
            (riscv_process_one_target_attr): Ditto.
            (riscv_process_target_attr): Ditto.
