[Committed] S/390: Fix trailing whitespaces

Hi,
I've committed the attached patch fixing several trailing whitespace
issues in the S/390 back-end which crept in over time. I personally
don't care enough about these kind of things to fix it. But there are
actually people complaining about this. Since it is that easy to make
them happy ...
Before applying I've made sure that the back-end still compiles.
Bye,
-Andreas-
