So that you can "git fetch" and review, and I might actually help you 
developing in the long run, so I need to push my changes somewhere ;-)

Okey. I just replicated the way you create tech files and tech includes.
I could just skip the gcc part and just directly include it into your 
scmos.tech generation.
It looked kind of odd anyway that you're using gcc for generating the tech 
file.
