    [GOLD] Set non-exec stack for ppc64
    
    gcc doesn't emit stack notes for ELFv1, since ELFv1 never needs an
    executable stack.  Note that ELFv1 is usually big-endian and ELFv2
    little-endian, but the ABI is really orthogonal to endiannes.
    
    	* powerpc.cc (Target_powerpc<64,*>::powerpc_info): Set
    	is_default_stack_executable false.
    
    (cherry picked from commit ec76901011c5af6a565936d4ad87247c51901b58)
