Add biarch support for "struct iovec". * defs.h (personality_wordsize): Add. * io.c [HAVE_SYS_UIO_H] (tprint_iov): [LINUX && SUPPORTED_PERSONALITIES > 1] Handle 32-bit personality. * util.c [HAVE_SYS_UIO_H] (dumpiov): [LINUX && SUPPORTED_PERSONALITIES > 1] Likewise. Patch from Jakub Jelinek. Fixes RH#218433.
