So you disable neon but do not choose a particular implementation which allows so. e.g. you should have -mtune=cortex-a9 which allows neon to be optional
but thats probably just the semantic thing. Below code should check for __ARM_NEON__ internal define being set as well before resorting to use neon instructions.
