794fcf79a8 Rename CONFIG_FFT_FLOAT ---> FFT_FLOAT
The define does not originate from configure, so it should not
have a name that is CONFIG_-prefixed.

92dad6687f arm: fix use of uninitialised value in ff_fft_fixed_init_arm()
When initialising an FFTContext for a plain FFT, mdct_bits is not set
and can contain a garbage value.  Since nbits is always valid and for
MDCT operation is mdct_bits - 2 checking this instead avoids using an
uninitialised value while having the same effect.

d526c5338d ARM: allow runtime masking of CPU features
This allows masking CPU features with the -cpuflags avconv option
which is useful for testing different optimisations without rebuilding.
