exec stack and pthread_exit () problem

Subject: exec stack and pthread_exit () problem

When I used --as-needed -lgcc_s --no-as-needed to replace -lgcc_eh,
I got random segfault on nptl/tst-execstack. I noticed that the main
thread changed the stack to executable and then called pthread_exit. It
seems that depending on the timing, the waiter thread would segfault.
The following patch fixes the segfault. Does pthread_exit in nptl do
anything to stack permission?
