libffi won't compile on arm (without FPU support)

[Kyle Tinker]

AG:

Good to hear!  If you need access to my toolchain, I can probably 
provide you a VMWare image of my toolchain on Ubuntu 10.04.

Let me know if you want that--it might be more efficient than doing it 
on Linux.

PS:  My toolchain isn't actually a mac--it's an embedded Linux device. 
But it has a lot of similarities to the mac build.

Thanks,
