Soletta Project is a framework for making IoT devices. With Soletta Project's libraries developers can easily write software for devices that control actuators/sensors and communicate using standard technologies. It enables adding smartness even on the smallest edge devices.
Also make the arctangent node, which is an out-of-tree node contribution node+sample example, depend on the sample being built.
The Fedora packaging build won't have samples built anymore, thus this cleanup.
