Vijay,

  Pthread support is in the libc/sys/linux directory in the form of 
linuxthreads, however, the linux directory hasn't been set up for non-x86 
systems such as arm.

  Work is needed to provide the linux machine directories for arm which 
supplies the basic syscall mechanism among other things.  Since the linux 
directory is LGPL, this code can be derived from glibc.  If you are willing to 
start this, I will be more than happy to assist you.

  An alternative you might look into is libpth http://www.gnu.org/software/pth/
