This avoids aliasing issues with GCC 6 in -fno-strict-aliasing mode. (With implicit padding, not all data is copied.) This change makes it explicit that struct sockaddr_storage is only 126 bytes large on m68k (unlike elsewhere, where we end up with the requested 128 bytes). The new test case makes sure that this does not happen on other architectures.
