Enable semaphores for ConnectCore9P Embedded Linux

I have an existing project using semaphores for IPC.
After porting this to the ConnecCore9P Dev. Board the
sem_open() is reported as “Not Implemented”. I checked
that IPC is enabled in the kernel but it seems that uclibc
must be recompiled. Can somebody provide the build configuration for the uclibc provided by Digi so I can take
that and just add IPC?

Thanks a lot for your help.
