System:
  Linux apps 2.6.38-11-generic #48-Ubuntu SMP Fri Jul 29 19:02:55 UTC 2011
x86_64 x86_64 x86_64 GNU/Linux

Buildroot:

  Config file attached.

Test program:
  http://blog.superpat.com/2010/07/14/semaphores-on-linux-sem_init-vs-sem_open/

If this program is build with dynamic library it fail when run on sem_init()
with error: "Function not implemented".

Semaphores on my system works,  for example, when I use semget().
Program can be linked as static or dynamic executable.
Example program from:
 http://www.cs.uregina.ca/Links/class-info/330/Semaphore/semaphore.html
program7_1.cpp

--- Comment #6 from Thomas Petazzoni <thomas.petazzoni@free-electrons.com> 2012-01-31 22:42:36 UTC ---
The original problem is that statically linking with pthread doesn't work with
uClibc. It is a known problem, which has been discussed on the uClibc
mailing-list already:
http://lists.uclibc.org/pipermail/uclibc/2011-March/045109.html. I haven't
heard of it being fixed, though. As it is not a Buildroot bug, but a uClibc
bug, I will be closing this bug, and I encourage you to report the problem to
the uClibc people.
