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. Signed-off-by: Sven Eckelmann <sven@open-mesh.com> SVN-Revision: 38851
