MontaVista noticed that when their kernels were configured to trap on unaligned
access gethostbyname_r could mysteriously crash.  I tracked this down to an
unaligned buffer being passed to gethostbyname_r from some other part of uClibc
(afraid I don't remember where from any more).  We have to pad the beginning of
the buffer to a pointer alignment before we store pointers in it.
