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  		+=3D -fPIC

...

Or maybe stack protection on bootx_init doesn't make much sense and we=20
could just do the following ?

CFLAGS_bootx_init.o  		+=3D -fPIC $(call cc-option, -fno-stack-protector)

That would be fine by me.

cheers
