    RISC-V: Eliminate unused parameter warning.
    
    The parameter orig_fndecl is not used, use anonymous parameters instead.
    
    ../.././gcc/gcc/config/riscv/riscv-c.cc: In function ‘bool riscv_check_builtin_call(location_t, vec<unsigned int>, tree, tree, unsigned int, tree_node**)’:
    ../.././gcc/gcc/config/riscv/riscv-c.cc:207:11: warning: unused parameter ‘orig_fndecl’ [-Wunused-parameter]
          tree orig_fndecl, unsigned int nargs, tree *args)
               ^~~~~~~~~~~
    
    gcc/ChangeLog:
    
            * config/riscv/riscv-c.cc (riscv_check_builtin_call): Eliminate warning.
    
    (cherry picked from commit 80f466aa1cce2759112c8b0121964d1bbb158f25)
