    Use default sub-segment align for non-ELF powerpc
    
    Defining this to zero for COFF and PE meant that code sections were
    padded with zeros.  The fact that no one has complained since 2006
    says these targets are dead, I guess.
    
    	* config/tc-ppc.h (SUB_SEGMENT_ALIGN): Define only for ELF.
