At least the current crop of Aarch64 HW can support running 32 bit EL0
code. Before we can build and test we need a minimal set of packages
installed. We can't use "apt build-dep" because it currently gets
confused trying to keep two sets of build-deps installed at once.
Instead we install a minimal set of libraries that will allow us to
continue.
