S/390 patch for binutils-2.10

[schwidefsky at de dot ibm dot com]

Good afternoon,
contained in this note you will find the binutils patch for linux on the
S/390.
I checked out from the current cvs repository on August 29 and created
the patch based on that version. I am sorry for the delay but the FSF
paperwork took some time to complete. It is one its way.
The patch comes in three parts:
1) binutils-s390-core.diff MD5 checksum 6303cfba6712b208e3c31cc5d48186e0
   Contains the bfd backend for elf_s390, the opcode definitions and the
   assembler.
2) binutils-s390-makefiles.diff MD5 checksum
186c64de6744c66e44343f4676e06577
   Contains all the changes in the Makefiles.
3) binutils-s390-config.diff MD5 checksum 8388102907cb47135898bed8bc921a3e
   Contains all the changes in the configuration files (config.guess,
config.sub
   and so on).

After I created the diffs and sent the patches on their way to get the
laywers
blessing I unfortunatly found another bug. I though it a good idea to
separate
the relocations for the PLT entries from the rest of the relocations. Can't
do
that because the dynamic linker doesn't like it. Here is the patch for this
problem that has to be applied on top of the core patch:

-          break;
         }
     }

Last but not least the ChangeLog entries. I separated them from the
patch because they will look different anyway.
