    [GOLD] PowerPC64 relocation overflow for -Os register save/restore funcs
    
    Fixes a silly mistake in calculating the address of -Os out-of-line
    register save/restore function copies.  Copies of these linker defined
    functions are added to stub sections when the original (in
    target->savres_section) can't be reached.
    
            * powerpc.cc (Target_powerpc::Relocate::relocate): Correct address
            calculation of out-of-line save/restore function copies.
    
    (cherry picked from commit 89c905a342d2cb35ebc4d66ad7cdca581b5134c3)
