[PATCH] Fix manythreads test case on s390

[Ulrich Weigand <weigand@i1.informatik.uni-erlangen.de>]

Hello,

the new manythreads.c test case fails on s390 when using NPTL,
because it tries to create 256 threads with default thread stack
size (which happens to be 8MB for NPTL).  This is hard to do
when the total address space size is 2 GB...

This can be fixed by using pthread_addr_setstacksize to reduce
the thread stack size.

Bye,
Ulrich

ChangeLog:

	* gdb.threads/manythreads.c: Reduce thread stack size.
