error: ‘__PTHREAD_SPINS’ was not declared in this scope

Hi,
I am using the following machine:
Arch: PPC64LE
OS: Ubuntu Linux 14.04
Output of uname -a:
Linux fs3 3.19.0-42-generic #48~14.04.1-Ubuntu SMP Fri Dec 18 10:24:40 UTC 2015 ppc64le ppc64le ppc64le GNU/Linux

After applying the #3586, the tests pass successfully for 4 gpu's. But, when I did "make clean" and tried to rebuild again, I got an unexpected error as shown below:

CXX src/gtest/gtest-all.cpp

I did a google search and found that __PTHREAD_SPINS is part of glibc and is present in pthreadtypes.h file.

Any idea folks?

Thanks in advance,

Sorry guys. It was a broken libc issue. Resolved it after reinstalling libc6 in ubuntu.
