* hurd/hurdchdir.c (_hurd_change_directory_port_from_name):
Allocate three, not two, more than LEN when appending '/.'.
* sysdeps/mach/hurd/chroot.c (chroot): Likewise. Don't check
if NAME ends with '/.' if it is shorter than 2 chars.
* mach/Makefile ($(mach-syscalls:%=$(objpfx)%.S)): Make the generated
files #include <sysdep.h> instead of <mach/machine/syscall_sw.h>.
