Subject: [PATCH] Adjust "erlang-base-hipe" installation to only happen if the
 package is available

This also updates "generate-stackbrew-library.sh" to exclude "ppc64le" from the Debian variant given that upstream's repository doesn't have an "Architectures" entry (and supporting files) for it yet.
