Arduino is basically a simplified/streamlined cross-compilation toolchain with very tightly coupled IDE integration.

I'd just provide a .sample and tell people what to do with it in the README. The alternative is to provide config.h as is and tell people to use "git update-index --assume-unchanged" immediately after cloning to ignore changes to the file, but this is prone to people accidentally committing credentials.
