Whether to use soft or hard float is a matter of compiler settings.
This flag just tells interested pieces that float should be avoided. 
Basically, the audio pipeline will run in fixed-point mode. If the audio codec 
provides no fixed-point support, VLC will at least convert to fixed-point 
before filtering and output (to PulseAudio).

If you know how to run-time detect A9 processors, we can add a check. But I 
daresay those aren't on my radar at the moment.
