Thanks, much better, s390x glibc now builds and even the testresults look good.
The only problems are 2 ICEs on 2 testcases.
Haven't had time to build trunk with your patch yet and verify nor distill
small self-contained testcases from it, but just in case you'd like to start
looking into it tomorrow, I've uploaded them to:
ftp://people.redhat.com/jakub/gcc/s390_ice/
In both cases the ICE is in change_address_1:
      if (reload_in_progress || reload_completed)
        gcc_assert (memory_address_p (mode, addr));	<= here
