You cannot expect a random binary taken from your vendor to work with a
random version/configuration of uClibc. Basically, you need to get the
source code for this application and recompile it with the toolchain
used to build your embedded system.

The uClibc library does not provide a stable ABI, both accross versions
and configurations.
