Hi this is a build problem. Due to cross compile accidently RDTCSP support is 
enabled, though it is not available on Phi. I already added a fix.

Hi, I did not usph it to google repo yet. Usually I link fix checkins to issue 
tickets. So as long as the ticket is still open it is not in the Google Repo 
yet.

I do some more testing on Phi now and then push the changes.

Jan

If you want to pull the changes you need to checkout the v3.1 branch.

Hi, With -C he also tries to pin the threads. This only works out if your 
binary is dynamically linked. Also you must call make install as the path to 
the according library is hardcoded into likwid binaries.
