With which options did you compile blahblah?  Can you show us the
(full) output of arm-iwmmxt-linux-gnu-gcc -v when you compile it?

Maybe, depending on your compile options.

Your libappbase-xscale-r.so was probably built using gcc 3.3.x, which
has libstdc++.so.5.  Since you don't have any source, you'll need to
rebuild the programs you try to link against it with gcc-3.3.x.
