    powerpc: Fix error message during relocation overflow
    
    The function _itoa_word() writes characters from the higher address to
    the lower address, requiring the destination string to reserve that size
    before calling it.
    
    	* sysdeps/powerpc/powerpc64/dl-machine.c (_dl_reloc_overflow):
    	Reserve 16 chars to reloc_addr before calling _itoa_word.
