These are standard gcc ARMv7A flags, to be sure it can run on ant A9,
which not all of them have NEON.

Since there's no __ARM_FP_D16 in ACLE, the idea is to use __ARM_NEON
as a D32 detection, since there's no point in having 32 D registers
without NEON, and AFAIK, there aren't any ARMv7 boards with VFPv3-D32
without NEON.

It may not be perfect, but if there is any board out there, we can
always ask ARM to add a new macro to ACLE.
