Pie is not supported

Hi,
I’m trying to use meta-riscv with Poky. The build is fine. Howerver, when using elf toolchain,the pie is not supported as

Can you please give me few hints?
I’m just a newbie with poky and meta-riscv.
Thank you

@chipsme I think the problem perhaps is in meta/conf/distro/include/security_flags.inc

GCCPIE ?= "--enable-default-pie"

perhaps we should define it to empty string in conf/machine/ baremetal-riscv64.conf
