fix division by zero in target_read_string()
Under certain circumstances, a floating point exception in
target_read_string() can happen when the type has been obtained
by a call to stpy_lazy_string_elt_type(). In the latter function,
a call to check_typedef() has been forgotten. This makes
type->length = 0 in this case.
