This seems to only occur when
-DBUILD_GRAPHICS=OFF.pavanky commentedon Jun 25, 2017
@mlloreda This is also only happening when I use regular blas / cblas / lapack / lapacke packages (which are single threaded) instead of openblas (which is multi threaded).
It's probably happening because the symbol is inherited from libraries that have pthread already linked to them.

@umar456 do you think it is a good idea to link all libaf* with thread libraries?

Fixed via #1872
