powerpc: Fix error message during relocation overflow

Browse Source 
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.
