Teleport: ARM/ARM64 packages

[webvictim]

Feature Request

We should have arm/arm64 RPM/DEB packages available for download.

Motivation

At the moment installing Teleport on a Raspberry Pi or other ARM device is still a very manual process. It'd be good to offer a convenient package format that people using these devices can leverage for installation.

Potential issues

Our download page will get busier with all these extra builds being displayed, plus the build process will need to run more parallel jobs. We also need to store more builds for each release.

Who's it for?

OSS User, Pro, Enterprise

Once completed we should also support ARM Container Builds https://github.com/gravitational/teleport/issues/3384

Looking forward to ARM64 support. We'd like to try it on Amazon's EC2 T2g instances.

The PR adding arm64 tarballs has been merged, but is pending support being added to the download portal for showing those builds. Once it's ready, I'll release Teleport 4.4.2 with arm64 builds available.

ARM/ARM64 RPM/DEB packages are a little way off yet.

arm64 tarballs for 4.4.2 are out: https://gravitational.com/teleport/download

These binaries don't work for me on my Jetson AGX:

$ teleport --help

I was able to work around this by making the modification suggested by @gclawes here: https://github.com/gravitational/teleport/issues/3384#issuecomment-735456862

Following that change, a make docker produces valid binaries in build/.

$ ls -lht ./build

@didiersmith Thanks for the information. I've added the AGX to the compatibility matrix I'm building here: https://github.com/gravitational/teleport/issues/4754#issuecomment-749587441
