Yes, I could do

  `if ARGUMENTS.get('arch', 'some default')`

but I would have to duplicate the logic to set the default value (which
I already had to add to

  `vars.Add('arch', 'some default')`

which is one of the reasons why I used the term "kludge"...

I admit this is only a minor issue, but still I think SCons should
provide a more elegant way to solve this.
