Introducing the aufs-util target recipe. This would be used in
conjuction with the aufs kernel feature to provide union mounts suitable
for live boot applications.
Only the target binaries are currently packages, with man pages,
libraries and other artifacts skipped in this initial integration.
(Integration work done by Bruce Ashfield <bruce.ashfield@windriver.com>
and Chen Qi <Qi.Chen@windriver.com> .)

+
+In a cross compilation environment, c2sh, c2tmac and ver need to be created first.

+Subject: [PATCH] aufs-util: don't strip executables
+
+By default, aufs-util strips its binaries. This produces QA warnings
+as follows:
+
+ WARNING: File '/sbin/mount.aufs' from aufs-util was already stripped, this will prevent future debugging!
+ WARNING: File '/sbin/auplink' from aufs-util was already stripped, this will prevent future debugging!
+ WARNING: File '/sbin/umount.aufs' from aufs-util was already stripped, this will prevent future debugging!
+ WARNING: File '/sbin/auibusy' from aufs-util was already stripped, this will prevent future debugging!
+ WARNING: File '/usr/lib/libau.so.2.6' from aufs-util was already stripped, this will prevent future debugging!
+
+To prevent this, we remove -s from LDFLAGS.
