-c is only used for compiling. Just drop it if you want to link. Also,
you should probably link C++ applications using g++ in order to pull in
the C++ libraries automatically. Finally, the object file should be
compiled using a cross compiler, not the host compiler (assuming you
are indeed cross-compiling.)
