What should I call the tune configuration file: tune-ppc440.inc or tune-ppc440-nf.inc ?

For the initial build tests, I will first try to get this running without a hardware FPU. By default the embedded PowerPC 440 processor on the Xilinx Virtex-5 doesn't have a hardware FPU. But one can configure a LogiCORE IP Virtex-5 APU Floating-Point Unit (v1.01a) to get single or double precision FPU support. 

How would I handle file naming and configuration for these 3 possible variants (i.e. software floating point emulation, hardware FPU single precision & hardware FPU double precision)?

Best regards,
