[FFmpeg-devel] [PATCH] libavcodec/mips: fix for mips optimized fp fft with hard coded tables disabled

From: Nedeljko Babic <nbabic at mips.com>

Floating point FFT (nips optimized) breaks when hard coded tables are
not enabled because MIPS optimization of floating point FFT uses only
ff_init_ff_cos_tabs(16) which is not enabled by default in that case.

This patch is fixing it.
