After the retirement of CONFIG_SCHED_EXIT_KILL_CHILDREN, [1]
the behavior is now effectively controlled by
CONFIG_SCHED_CHILD_STATUS, which is IMO confusing.
(It was even surprising me.)
This commit solves it by making HAVE_GROUP_MEMBERS
a synonym of !CONFIG_DISABLE_PTHREAD. I guess this change aligns
the intention of the CONFIG_SCHED_EXIT_KILL_CHILDREN retirement.
That is, always tries to be similar to the standard behavior.
Another option would be to revive CONFIG_SCHED_EXIT_KILL_CHILDREN
and make the HAVE_GROUP_MEMBERS logic aware of it.
It might be a good idea if we want a finer-grained control of
code to build. (One can argue his application uses pthread
but does never _exit. In that case, it might be a waste to maintain
group membership. I suspect it might not be too rare in embedded
world.)

Situation:
Assume we have 2 cpus, and busy run task0.
CPU0 CPU1
task0 -> task1 task2 -> task0
1. remove task0 form runninglist
2. take task1 as new tcb
3. add task0 to blocklist
4. clear spinlock
4.1 remove task2 form runninglist
4.2 take task0 as new tcb
4.3 add task2 to blocklist
4.4 use svc ISR swith to task0
4.5 crash
5. use svc ISR swith to task1
Fix:
Move clear spinlock to the end of svc ISR

in struct work_s:
union
{
struct
{
struct dq_entry_s dq; /* Implements a double linked list */
clock_t qtime; /* Time work queued */
} s;
struct wdog_s timer; /* Delay expiry timer */
}
while we use WDOG_ISACTIVE(&work->timer) to decide use dq or timer,
that is error, wd_cancel() maybe modify this area, dq_rem() also can
modify this area.
So we can't use the WDOG_ISACTIVE(&work->timer) to take as the judgement,
when there is a union.
Fix:
swap the order in struct wdog_s, move the arg to the second 32bit
