Firecracker PIE builds don't run on AArch64

[razvand]

Describe the bug

Unikraft static PIE builds for Firecracker on AArch64 don't work. The output message is:

Steps to reproduce

Build the app-helloworld Firecracker image with PIE for AArch64 using the commands:

git clone https://github.com/unikraft/app-helloworld helloworld
cd helloworld/
mkdir .unikraft
git clone https://github.com/unikraft/unikraft .unikraft/unikraft
wget https://raw.githubusercontent.com/unikraft-upb/maintainer-tools/staging/workdir/copy/base/apps/helloworld/.config.helloworld-fc-aarch64-pie
UK_DEFCONFIG=$(pwd)/.config.helloworld-fc-aarch64-pie make defconfig
make -j $(nproc)

To run the resulting image (build/helloworld_fc-arm64), you require an AArch64 baremetal system. Copy the resulting image on that system and run:

wget https://github.com/firecracker-microvm/firecracker/releases/download/v1.4.1/firecracker-v1.4.1-aarch64.tgz
tar xf firecracker-v1.4.1-aarch64.tgz
wget https://gist.githubusercontent.com/razvand/7c518132f23b3ca9a46824ae605f31c3/raw/4b847ebb62c2e8c517163fb102f72f238e7690ac/helloworld-fc-aarch64.json

Expected behavior

The unikernel image should run under Firecracker and print Hello, World!.
