arm: fft_vfp: Unify the behaviour in ff_fft_calc_vfp between arm/thumb
Don't include the function pointer table in the code segment in arm mode. This shouldn't have any significant performance effect. It does end up as a few more instructions than before, for ARM, but only at the entry to this function, not within the fft functions themselves. Signed-off-by: Martin Storsjö <martin@martin.st>
