Segher, any idea about this problem ?

Are you building as PIC? Are you linking libssp_nonshared.a? Why not?
Spotted, thanks.
arch/powerpc/platforms/powermac/Makefile contains:
CFLAGS_bootx_init.o += -fPIC
Does it mean we should add -lssp_nonshared to LDFLAGS_vmlinux ?
Or maybe stack protection on bootx_init doesn't make much sense and we
could just do the following ?
CFLAGS_bootx_init.o += -fPIC $(call cc-option, -fno-stack-protector)
