Subject: [PATCH] configure.ac: support large-file for stat64

While starting dbus-daemon on a 32-bit linux host and it invokes
fstat to load /etc/dbus-1/system.conf through NFS. If system.conf
was created with a large indoe number on 64-bit host. The above
fstat invoking failed. Here is the log of strace:
............
$ ls -i /etc/dbus-1/system.conf
53778558109 /etc/dbus-1/system.conf

$ strace /usr/bin/dbus-daemon --system --address=systemd: --nofork --nopidfile --systemd-activation
|open("/etc/dbus-1/system.conf", O_RDONLY) = 4
|fstat64(4, {st_mode=S_IFREG|0644, st_size=3340, ...}) = 0
|close(4) = 0
|close(3) = 0
|write(2, "Failed to start message bus: Fai"..., 109Failed to start message bus:
Failed to stat "/etc/dbus-1/system.conf": Value too large for defined data type
|) = 109
|exit_group(1) = ?
|+++ exited with 1 +++
............

In this situation, we should support large-file for stat64. Add marco
AC_SYS_LARGEFILE to do the detection at configure time. It can be disabled
by configuring with the `--disable-largefile' option.
