Comment:
Can we use musl's stuff instead, but renamed appropriately? I think it's clearer and has known provenance.

```
	union {
		char __pad[64 - 2*sizeof(int) - sizeof(union sigval)];
		pid_t sigev_notify_thread_id;
		struct {
			void (*sigev_notify_function)(union sigval);
			pthread_attr_t *sigev_notify_attributes;
		} __sev_thread;
	} __sev_fields;
```
