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.
