I tried it with (on s390x/ SUSE SLES8 ;-)
./configure --prefix=/xentric/volkdir/public/gdb --target=s390-ibm-linux-gnu
--host=s390-ibm-linux-gnu


And make brings folowing messages:

So I will go to plan B and look for an m31 gdb.

Are there plans to enable multilib debugging for s390-linux?

Thanks a lot so far.
