Building gambas on OBS

[munix9 <munix9@xxxxxxxxxxxxxx>]

Take a look at the result:

I don't know right now why Arch isn't showing up in the downloads - 
maybe a cache thing, so it might take a while.

This was created relatively quickly, so it may still have a few rough edges.

I stole the PKGBUILD for arch from their build-system and adapted it, as 
well as the Debian/Ubuntu config from their build-system.

And of course it's still not always easy to find the right setup for the 
different distributions - especially with Debian/Ubuntu, as the format 
of the build instructions is not as flexible as with rpm (my opinion).

The project configuration also sometimes needs to be adjusted:
