Cyclone in pd-extended is just a libdir library of Max/MSP compatible  
objectclasses.  When cyclone is built as one big library in one file,  
then there are some extra Max/MSP compatibility features.  If someone  
added the cyclone.pd_linux creation to the Pd-extended build system,  
then this would also be included.

Getting rid of cyclone's pow~ would break all of the patches that rely  
on cyclone's pow~, and would also make it harder to import Max/MSP  
patches.  Removing it is not a solution.
