FPU support for aarch64

Hi All,

I am using the linaro tool chain (4.9) to compile some programs on aarch64 simulated platform. But I am facing below erros

error: '_FPU_RC_DOWN' undeclared (first use in this function) (_FPU_RC_DOWN | _FPU_RC_UP | _FPU_RC_ZERO | _FPU_RC_NEAREST)

Possibly FPU support for the aarch64. I did search in the toolchain code but I dint find these flags for the aarch64, it present for others

Please let me how can I resolve this issue.

Regards, Pradeep
