-march=native was not included in GCC 5.1 that Linaro provided. I don't know
if Linaro has plans to backport the support it but it is already there for GCC
6.
You don't need -mfpu=neon for AARCH64 at all. AARCH64 defaults to having simd
turned on.

Hi Linaro Toolchain Group,
I have questions regarding -mfpu=neon and -march=native w.r.t aarch64
linaro native toolchain (aarch64-linux-gnu)
I found gcc is not accepting these flags.
On juno Board:
gcc -mfpu=neon hello.c -o hello
gcc: error: unrecognized command line option '-mfpu=neon'
gcc -ma
