[v2] linux-user: bigger default stack
PTHREAD_STACK_MIN (16KB) is somewhat inadequate for a new stack for new QEMU threads. Set new limit to 256K which should be enough, yet doesn't increase memory pressure significantly. Signed-off-by: Riku Voipio <riku.voipio@nokia.com> Reviewed-by: Nathan Froyd <froydnj@codesourcery.com>
