aarch64 toolchain support NEON and vfp features

Hi ,

I am a SW engineer that use Linaro-toolchain to build images,

Recently, I encounter some issue about enable NEON features on ARMv8 processor platform. I cat cpuinfo, can not find neon and vfp feature enable in list, the image was build with aarch-64 toolchian; While, the image built by armv7l toolchain can list "neon and vfp" in cpuinfo.

I want to verify from your side,

1. if the toolchain of aarch64 version already enable" neon and vfp " in default, Because I do not find some build items that related with "neon", 2. If not supported defaultly, can you give some suggestion to enable it.

Thanks & B.R. Joy Deng
