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.
