Ok I have rebuilt libbfd.a  (static lib) on the Xeon main server and
recompiled Score 5.4 (score and mpi) from source.

Everything is working fine on the Xeon nodes. 

scored.exe seems to have ia64 symbols:

nm /opt/score/deploy/bin.i386-redhat7-linux2_4/scored.exe | grep ia64  
08255d40 R bfd_efi_app_ia64_vec
08254ea0 R bfd_elf64_ia64_aix_big_vec
08255020 R bfd_elf64_ia64_aix_little_vec
08254aa0 R bfd_elf64_ia64_big_vec
082552a0 R bfd_elf64_ia64_hpux_big_vec
08254c20 R bfd_elf64_ia64_little_vec
08256440 R bfd_ia64_arch

etc

However I still have the same error:
 
server mpi:$ cat hosts
comp00.streamline
itanium01.streamline 
server mpi:$ scout -F hosts -e scrun -nodes=2x1 ./jacobi_mpi
SCOUT: Spawning done.            
FEP: Unable to connect with SCore-D (comp07)
FEP:WARNING checkpoint option is ignored in single-user mode.
<1> ULT:ERROR Unable to open binary file (/opt/score/deploy/bin.ia64-redhat-linux2_4/scored.exe)=0

The itanium01 bin.ia64-redhat-linux2_4 directories are mounted on the Xeon server as well.

server mpi:$ df
itanium01:/opt/score/deploy/bin.ia64-redhat-linux2_4
                      33171392  15447184  16039152  50% /opt/score/deploy/bin.ia64-redhat-linux2_4

Many thanks for your help.
