QEMU

This provides a few runnable targets:

• bazelisk run //debian/amd64/qemu-system-arm:qemu-system-aarch64
• bazelisk run //debian/arm64/qemu-system-arm:qemu-system-aarch64
• bazelisk run //debian/amd64/qemu-system-arm:qemu-system-x86_64
• bazelisk run //debian/arm64/qemu-system-arm:qemu-system-x86_64

These are then registered as a Bazel toolchain, which can be executed as so:

bazelisk run -- //labgrid/toolchain/qemu-system:resolved

That will provide the correct QEMU binary for the host system and target constraints.

bazelisk run -- //labgrid/toolchain/qemu-system:resolved --platforms=@toolchain_utils//toolchain/platform:arm64-linux

That will resolve to //debian/amd64/qemu-system-arm:qemu-system-aarch64, a QEMU system for amd64 host emulating arm64.
