Some success targeting PXA320 bare board, but link errors remain

[Rick Mann]

I've finally succeeded in building a GCC/newlib/libgcc that all  
support VFP instructions (the pre-built graphics library I'm forced  
to use was built with VFP).

Anyway, I had expected to need to implement things like _open_r(),  
but not any of the following. Can anyone tell me what I missed?

TIA,
Rick
