--- Comment #2 from Elvis Dowson <elvis.dowson at gmail.com> ---
I was able to progress a little bit by running the bootstrap command for the
arm64 architecture. Bootstrapping was mentioned for the macosx build, but the
documentation didn't state that it had to be run for every architecture that
you plan to build.

$ ./cerbero-uninstalled -c config/cross-ios-arm64.cbc bootstrap
$ ./cerbero-uninstalled -c config/cross-ios-arm64.cbc package gstreamer-1.0

However it fails a little further with bzip2:
