Changes

1. Take a look at the existing raspberrypi-vc package to see how it works. Notice that it uses a tarball containing prebuilt programs instead of the source code.

2. Experiment with a direct from-source build of the raspberrypi-vc code (forget about RPMs at first). Make sure you understand the build process well.

3. Modify the raspberrypi-vc package to build from source instead of using the prebuilt binaries.
