libpthread: pthread_exit in static app. segfaults
Static applications that call pthread_exit on the main thread segfault.
This is because after a thread terminates __uClibc_main decrements
__nptl_nthreads which is only defined in pthread_create.
Therefore the right solution is to add a requirement to pthread_create
from pthread_exit.
This patch has been backported from glibc tree:
