    Not a GCC expert, but it looks like its the ABI your using.

    In your build command you setting the floating point ABI as soft (pass floating point arguments in integer registers).  But the error message from the linker suggests that what you're linking against is built for hard float (pass floating point arguments in VFP registers).  You can't mix objects with different ABIs (at least not if you want them to work).
