Patch for the port directory.

Hi,

I have been issues building graphics/openpgl with the OpenMP multithreading
backend rather than TBB. It's not much :

- In openpgl/spatial/kdtree/KDTreeBuilder.h, updateTreeNode() calls are missing
their sample argument in OpenMP version (not in TBB), just add it

- In openpgl/spatial/KNN.h, a #pragma parallel for try to set the number of
cores from an inexistant variable, the TBB version do not set the number of
cores: remove the parameters.

The patches are in #ifdef-ed parts of the code and can be applied regardless of
the option selected. I will aslo add a poudriere build log for QA.

Thanks,
