Buildpacks are not aarch64?

[Xantios]

Summary

I run a Ubuntu VM through Vmware on a Apple M1 machine. i run Docker inside that VM and want to use pack. however when i try to run pack lifecycle dies with the error standard_init_linux.go:228: exec user process caused: exec format error

---

Reproduction

Steps

1. Install vmware Fusion Tech Preview
2. install ubuntu & docker VM
3. make pack from source because aarch64 is not yet availbe out of the box

Current behavior

standard_init_linux.go:228: exec user process caused: exec format error

Expected behavior

To grep aarch64 available images when available, use the --platform option otherwise? of maybe spit out an error?

@Xantios do you need to run pack inside the VM? pack build should work on Apple M1s if you are using emulation.

Closing as the lifecycle has linux-arm64 support for some time and there is a (limited) set of linux-arm64 buildpacks available. For more information on our multi-arch efforts, please see #1570
