I'm using gcc version 9.4.0 (Ubuntu 9.4.0-1ubuntu1~20.04.1) on Ubuntu 
20.04.4, from the Ubuntu repo.

I'm building it with:


export PACKAGES_PATH=$PWD/edk2:$PWD/edk2-platforms:$PWD/edk2-non-osi
export WORKSPACE=$PWD
export GCC5_AARCH64_PREFIX=aarch64-linux-gnu-

. ./edk2/edksetup.sh
build -p ./Features/Ext4Pkg/Ext4Pkg.dsc -a AARCH64 -b RELEASE -t GCC5


Some of the messages are:
