fixing build.sh not returning error in build (#1460)

Return the build status as return code from the `main` helper function.
In the process convert the handling if the file was sourced or directly
executed into an explicit if/else statement to make the intent clearer.

In case of an build error the error is now reported at the build step,
where the error happened.
