    RISC-V: Don't show support for 1.9.1 priv spec
    
    The privileged spec 1.9.1 support was removed since binutils 2.43. The
    linker only recognizes it and then reports a warning that it may
    conflict with other spec versions.
    
    While the support is removed, binutils should still recognize it, but it
    shouldn't be exposed to the user in `disassember-options` help.
