Test on different architectures

My script (put together from the history of the files, rather than a fully-tested script per se):

The commands to clone PDL, and get a sufficient (and parallel) build:

sudo apt-get install git build-essential gfortran libtest-warn-perl libtest-exception-perl libdevel-checklib-perl libpod-parser-perl libfile-which-perl libfile-map-perl libtest-deep-perl libextutils-f77-perl libinline-c-perl libterm-readkey-perl libextutils-depends-perl libastro-fits-header-perl
git clone https://github.com/PDLPorters/pdl.git
export MAKEFLAGS=--jobs=8 HARNESS_OPTIONS=j8

The Vagrantfile I used to debug on i386, which ran much quicker and was painless to set up:

Vagrant.configure("2") do |config|
  config.vm.box = "bento/debian-11.2-i386"
  config.vm.provider "virtualbox" do |v|
    v.memory = 4096
    v.cpus = 8
  end
end
