uClibc: Deactivate oversized thread stack cache
A small system like the common home router doesn't have 40 MiB per process for
a dirty stack cache. This can easily lead to an overbooking OOM problem and
caused a lot of hangs+reboots on 32 MiB systems running nodogsplash.
Not using a stack cache can increase the time to spawn new threads. This is
hopefully no problem for system not running a lot of parallel computations.
