Like this?

$ cat list-libs.sh
#!/bin/sh

binfiles="sh cat cp dd killall ls lsmod mkdir mknod mount "
binfiles="$binfiles umount sed sleep ln rm uname"

sbinfiles="udevadm udevd modprobe blkid switch_root mdadm"

$unsorted=$(mktemp /tmp/unsorted.XXXXXXXXXX)

for f in $binfiles; do
ldd /bin/$f | sed "s/\t//" | cut -d" " -f1 >> $unsorted
done

for f in $sbinfiles; do
ldd /sbin/$f | sed "s/\t//" | cut -d" " -f1 >> $unsorted
done

sort $unsorted | uniq | while read lib ; do
if [ "$lib" == "linux-vdso.so.1" ] ||
[ "$lib" == "linux-gate.so.1" ]; then
continue
fi

basename $lib
done

rm $unsorted
