Cross-Platform building errors

[HwangDozz]

I deployed three BuildKit daemon processes using Kubernetes StatefulSet. When building images with buildctl --addr pointing to these daemons, and using --platform "linux/amd64,linux/arm64" for cross-platform builds, I encountered an error.

here are the error messages: .buildkit_qemu_emulator: /usr/bin/bash: Invalid ELF image for this architecture

Can you show your Dockerfile please?
