Weird, because on line 46, we explicitly add a trainling '\n' :
    https://git.buildroot.org/buildroot/tree/support/testing/infra/basetest.py#n45

   45:  self.config = '\n'.join([line.lstrip() for line in
                                self.config.splitlines()]) + '\n'
   46:  self.config += "BR2_JLEVEL={}\n".format(self.jlevel)

Well, I doubt this is useful. Just prepend a \n, if it really is useful :

    self.config += "\nBR2_JLEVEL={}\n".format(self.jlevel)

Yes, that would probably be better.
