[NDS32] Add new function nds32_cpu_cpp_builtins and use it for TARGET_CPU_CPP_BUILTINS.

gcc/
	* config/nds32/nds32-protos.h (nds32_cpu_cpp_builtins): Declare
	function.
	* config/nds32/nds32.c (nds32_cpu_cpp_builtins): New function.
	* config/nds32/nds32.h (TARGET_CPU_CPP_BUILTINS): Modify its
	definition.
