I'm getting linker errors when trying to use NN functions, they are not pre-compiled like the DSP.

@sandeepmistry do you think they are not precompiled because they use some features not commonly deployed across a microarchitecture family? In that case the only thing I can think about is turning them into Arduino libraries (which is bad, but not terrible, since CMSIS changes are in sync with the core)
