    Fix RISC-V bootstrap
    
    Recent changes from Kito have an unused parameter.  On the assumption that he's
    going to likely want it as part of the API, I've simply removed the parameter's
    name until such time as Kito needs it.
    
    This should restore bootstrapping to the RISC-V port.  Committing now rather
    than waiting for the CI system given bootstrap builds currently fail.
    
            * config/riscv/riscv.cc (riscv_arg_partial_bytes): Remove name
            from unused parameter.
    
    (cherry picked from commit 86a5e7770caad6d5449b19d66f8f1b32b89abea0)
