Do not define DFP builtin functions, if DFP has been disabled.
PR bootstrap/92661
* config/rs6000/rs6000-call.c: (def_builtin): Do not define the
builtin if we don't have an actual type.
(builtin_function_type): If the builtin function uses a DFP type
and decimal float has been disabled, then return NULL_TREE.
