Wainer dos Santos Moschetta 0f7950fb2a packaging: configure QEMU with -O2

Currently the the configure-hypervisor.sh doesn't set any optimization flag when
compiling QEMU >= 5.2.0 since the configure script will implicitly set -O2 on Ubuntu. But
on other environments, for example CentOS 7, it won't be set any optimization and this
results on the compiler warn:

  # warning _FORTIFY_SOURCE requires compiling with optimization (-O)

To avoid this inconsistent behavior across different build environments, let's explicitly
set the -O2 flag.

Packaging scripts

This directory contains useful packaging scripts.

`configure-hypervisor.sh`

This script generates the official set of QEMU-based hypervisor build configuration options. All repositories that need to build a hypervisor from source MUST use this script to ensure the hypervisor is built in a known way since using a different set of options can impact many areas including performance, memory footprint and security.

Example usage:

  $ configure-hypervisor.sh qemu
