Sven Neumann 38bab3635a opus: allow to select fixed-point implementation
The default of choosing the fixed-point implementation if
the target hardware does not have floating-point unit is not
always the best choice. Modern ARM hardware has floating
point support but most likely the fixed-point implementation
in Opus will still perform better. In particular if your CPU
supports the NEON extension.

This commit allows to select the fixed-point implementation
manually and sets the default based on the availability of
a floating-point unit.

[Peter: force option for sw float, slightly reword]

The Opus codec is designed for interactive speech and audio
transmission over the Internet. It is designed by the IETF
Codec Working Group and incorporates technology from Skype's
SILK codec and Xiph.Org's CELT codec.
It is intended to suit a wide range of interactive audio
applications, including Voice over IP, videoconferencing,
in-game chat, and even remote live music performances. It
can scale from low bit-rate narrowband speech to very high
quality stereo music.

Compile without floating point operations (for machines
without a fast enough FPU).
