OK, I found a reference to a related issue on Intel's forum:
http://software.intel.com/en-us/forums/intel-math-kernel-library/topic/62502/
Still the same issue than the one I has some months ago with Intel
decision to change the link stage.

I've tried with search_static_first=1, but it still picks up the .so libraries.
