The given patches weren't enough :-(   The resulted GNU linker complained
about not finding the output format etc.  A quick "how these things were 
done
in 'alpha', 'i386' etc." comparison revealed that also the 'ld/emulparams'
directory required the following patch in the current 
'binutils-2.17.50.0.3' :

---------------- clip ----------------------------
*** elf_x86_64_fbsd.sh.orig     Thu Mar  7 21:52:39 2002
--- elf_x86_64_fbsd.sh  Tue Jul 18 15:06:58 2006
***************

  . ${srcdir}/emulparams/elf_x86_64.sh
  . ${srcdir}/emulparams/elf_fbsd.sh
+ OUTPUT_FORMAT="elf64-x86-64-freebsd"
---------------- clip ----------------------------


After adding this the produced binutils gave right labeled executables and
more importantly the crosscompilers to the 'x86_64-freebsd6.1' target
could be built, giving seemingly OK shared libraries with the following:

kai@Dell:/data1/home/src/gcc-4.0.3/build/gcc> readelf -h libgcc_s.so.1

output got via the 'readelf -h'...
