/lib/security on root disk

[Philip Blundell <philb@gnu.org>]

This change (in rootdisk.sh version 1.279) breaks the build for me, on arm.  I 
don't have a lib/security directory.  Are s390 shipping PAM on the root disk?!

-    EXECUTABLES=$(find $R/{bin,sbin,lib,usr/bin,usr/sbin,usr/lib} -maxdepth 1 
-type f)
+    EXECUTABLES=$(find $R/{bin,sbin,lib,lib/security,usr/bin,usr/sbin,usr/lib}
 -maxdepth 1 -type f)

I: adding dbootstrap
I: doing library reduction
find: /var/tmp/boot-floppies/root-tmp-20165/lib/security: No such file or 
directory
E: ./rootdisk.sh abort
