ARM: disable ff_vector_fmul_vfp on VFPv3 systems
This function uses old-style vector operations deprecated in VFPv3. Some implementations, e.g. Cortex-A9, support them only through slow software emulation. Cortex-A8 does have this functionality in hardware, but as it also has NEON, this function is not used there regardless. Signed-off-by: Mans Rullgard <mans@mansr.com>
