I built powerpc-elf- binutils with --enable-targets=powerpc64-elf,  
which added above elf64ppc to -V...

LD=powerpc64-elf-ld does solve the above but leaves me with:

PMG5-2:obj-ppc64 andreas$ make V=1 LD="powerpc64-elf-ld"
powerpc64-elf-ld --warn-common -N -T ../arch/ppc64/qemu/ldscript -o  
openbios-qemu.elf.nostrip --whole-archive target/arch/ppc/qemu/start.o  
target/arch/ppc/timebase.o libqemu.a libbootstrap.a libopenbios.a

ldscript is unchanged except for the output format.
