Apart from one small hardcoded check on Fedora for java version,
most code is arch-independant (python).
fpm defaults to arch <all> or the native one when building the DEB
packages, so use an explicit set for arch <all> in all fpm builds.
TODO:
Extend check for `uname -m` result for aarch64 and other platforms
in <networking_odl/devstack/setup_java.sh>.
