AI85 Fix Build Errors

[Jake-Carter]

This PR fixes misc. build errors for the AI85 projects.

All examples with the exception of "mnist-streaming" (see https://jira.maxim-ic.com/browse/MSDK-746) should build cleanly.

Resolves #6 - The Github migration missed some updates to a few projects. "config.h" has been renamed "example_config.h" to avoid conflicts with external libraries

@Jake-Carter I'm still getting some build errors.

This is the script I'm running from Examples/MAX78000

#/bin/bash

# Find all of the examples
SUBDIRS=$(find . -mindepth 2 -name "?akefile" -printf '%h\n')

for dir in ${SUBDIRS}
do
    make -C ${dir} clean
    make -C ${dir} -j8
done

Hey @kevin-gillespie, mnist-streaming is the only broken project. See https://jira.maxim-ic.com/browse/MSDK-746

It's taking a bit more work to get updated. For some reason the CNN is embedded inside of the main source files with an older kernel format, so it's not trivial to get it updated with the latest missing CNN files. Working on fixing it

Ok I'll skip that example for now. I figured it was just a simple problem with missing files.
