use build_function_type_list in the picochip backend

As $SUBJECT suggests.  Tested with cross to picochip-elf.  OK to commit?

-Nathan

	* config/picochip/picochip.c (picochip_init_builtins): Call
	build_function_type_list instead of build_function_type.
	Delete `endlink' variable.

Looks good to me Nathan. Please go ahead and commit.

Thanks
Hari
