Thanks for checking the build!  

In the log snippet, we see:

The build -- seems like the configure step -- is attempting to link with "-
lpthreads".  This does not happen in previous successful builds [1].   In 
fact, the test build "CheckFunctionExists.c.o" does not appear in successful 
build logs.  Something is different in your environment.  

Or maybe with opencv 3.1.  I see you have uploaded to experimental; will try a 
build myself.
