So, something went wrong, unit test binary is linked with libpthread
testegw# ldd llvmunittest_ADT
llvmunittest_ADT:
libthr.so.2 => /usr/lib/libthr.so.2 (0x8006e7000)
libstdc++.so.6 => /usr/local/lib/gcc42/libstdc++.so.6 (0x8007fe000)
libm.so.4 => /lib/libm.so.4 (0x800a0a000)
libgcc_s.so.1 => /usr/local/lib/gcc42/libgcc_s.so.1 (0x800b26000)
libpthread.so.2 => /lib/libpthread.so.2 (0x800c33000)
libc.so.6 => /lib/libc.so.6 (0x800d5e000)
