Ah, my favourite processor :)

I see

Target options -> Floating point -> hardware(FPU) which should almost
certainly be "softfp" as I doubt MaverickCrunch FPU code generation
works. That should also allow you to link objects with standard Debian
or whatever - it certainly won't work with the arm hardfloat ports
like debian armhf, which neds a VFP FPU.

Let me know if that makes any difference.
