Missing function arm_user_jop_disabled due to __has_feature(ptrauth) in XNU kernel

#if __has_feature(ptrauth_calls)
boolean_t
arm_user_jop_disabled(void)
{
    return FALSE;
}
#endif /* __has_feature(ptrauth_calls) */

This function is only declared when this feature is present. This leads to the following error:

call to undeclared function 'arm_user_jop_disabled'; ISO C99 and later do not support implicit function declarations
