Fix:

  target/sparc/translate.c:2823:66: error: declaration shadows a variable in the global scope [-Werror,-Wshadow]
  static void gen_load_trap_state_at_tl(TCGv_ptr r_tsptr, TCGv_env tcg_env)
                                                                   ^
  include/tcg/tcg.h:579:17: note: previous declaration is here
  extern TCGv_env tcg_env;
                  ^
