 When I look to build an x86_64 version of rust under rosetta `arch -x86-64
 /bin/zsh`, it fails with:

 Why would I want to do this relatively exotic build? Because Circle CI is
 getting ready to get rid of all Intel build bots and so this is how I will
 have to build the intel version.

 This would not be an issue if macports could use pre-built binaries for
 rust when building in a custom location and without sudo, but I don't
 think that's how it work.
