avutil: turn arm setend into a cpuflag this allows disabling and enabling it it also prevents crashes if vfpv3 and neon are disabled which previously would have enabled the flag And last but not least one can enable setend on cpus like cortex-a8 where its fast but disabled by default Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
