Use objdump to do library depency check 

Generally, things that are trying to determine shared library
dependencies should use something like objdump, not ldd:

objdump -p $f | awk '/ NEEDED / { print $2 }'

    because many times it is necessary to find out the depending libraries of an executable but ldd is not available. This happens a lot on embedded systems that runs Linux.

    Also, on x86, ldd attempt to actually run the application. If this cannot happen (e.g. because you attempt to run a 32-bit app on a 64-bit Linux and no 32-bit compatibility is present), you don't get output at all.
