Odot objects behaving strangely on Raspberry Pi #428

Matthew Goodheart writes "I'm running into problems with running odot in PD on a Pi. I've got the latest CNMAT externals installed, but o.pack doesn't seem to recognize the input, giving the "-nan" error. There are no problems with strings or lists."

This is/was caused by duplicate symbols. o.route, o.select, and o.atomize all share the same code, and their functions all begin with the same prefix (oroute_). It seems that these libraries are being loaded differently on OS X and Linux. I added a quick fix that mangles the function names to make them unique for the different objects.

@maccallum FYI, I just resolved a similar issue with randdist, which was throwing duplicate symbols for various architectures on compile. Apparently, updating the Xcode project flipped the switch on Apple Clang - Code Generation > No Common Blocks from "No" to "Yes". Switching this back to "No" in the Xcode project allows build without the Duplicate Symbols error.
