Run objdump on your newlib libc.a library and look through the disassembly
to verify whether or not it has any FP instructions present. AIUI, the PXA
series don't have FP hardware, so your symptoms are just what you'd expect if
you'd got the compiler ok but newlib was compiled hard float.
Can't think of a witty .sigline today....
