From a12dfe9be05f9dee96c7637a20c01e05711c563c Mon Sep 17 00:00:00 2001
From: David Michael <david.michael@coreos.com>
Date: Sun, 7 Jan 11:26:57 2018 -0500
Subject: [PATCH] arm64: Set -fno-PIC along with -mcmodel=large
As seen in GCC's gcc/config/aarch64/aarch64.c, -fPIC with large
code model is unsupported. This fixes the "sorry, unimplemented"
errors when building with compilers defaulting to -fPIC.
