Subject: Merge in the pthread library.  This is the linuxthreads library taken
 from glibc 2.1.3 and ported to work with uClibc by Stefan Soucek and Erik
 Andersen (me).  Stefan has hacked things up such that linuxthreads runs on
 MMU-less systems (tested only on arm-nommu).  Erik cleaned things up and made
 it work properly as a shared library.  -Erik
