Cleanup page about building with cerbero
All platform specific where hard to follow as "information", make proper paragapgraph about those requirements And pass the file into ``pandoc -t markdown --reference-links --atx-headers` making the whoel file much nicer to read.`

The GStreamer SDK build system provides bootstrapping facilities for all

platforms, but it still needs a minimum base to bootstrap:
