Just compiling one file is not my (and others) problem.
As you can see the problem appears during linking. There is a little bit more
stuff to do for a uC hex-file.

Currently I'm working with a self compiled toolchain  in ~/bin/.
Not the first time and not the first software package with OpenSuSE.

It should be possible with a simple installation of needed packges to run the
workflow.
