[iOS8] fix kAudioFormatFlagsCanonical deprecation warning

[borg]

Trying to compile for iOS8 I updated wscript to SDKVER="8.0"
but I still get compile errors.

Reports successful but in Xcode:

I didn't try in iOS7 and haven't got that SDK any longer so not sure what to expect. Should it work?

Is pkg-config required?
Checking for program pkg-config : not found

Many thanks!

Nevermind, easier to just include the source

The deprecation warning should not be much of a problem yet. I will look into it.

The no symbols warnings are normal, since you compile without libav* or libsndfile.

The missing aubio_pitchdetection is strange, since there is no symbol with such name in the library. Maybe something you modified on your copy?
