Release 32.1.1 fails at enableCrossCompilation on Debian with qemu-user-static installed

[migrym]

Building a hello world application fails on Debian 13 (with podman, podman-docker, and qemu-user-static installed):

/home/jpm/tmp/c/helloworld/ADF was regenerated successfully
/home/jpm/tmp/c/helloworld/Dockerfile was regenerated successfully
Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.
Error: short-name "multiarch/qemu-user-static" did not resolve to an alias and no unqualified-search registries are defined in "/etc/containers/registries.conf"
Error while building 'armv7l': failed to setup cross-compilation: exit status 125

Commenting the call to enableCrossCompilation in internal/builder/builder.go works around this issue:

diff --git a/internal/builder/builder.go b/internal/builder/builder.go

        args, err := prepareDockerBuildArgs(settings.Platform, buildSettings.Options, appDir, tmpBuildPath)
        if err != nil {

Being able to control if enableCrossCompilation gets called would fix the issue. Having e.g. a --no-cross-compilation option would allow users to keep the current behavior as default but disable the call on demand.

If enableCrossCompliation is disabled, the container image produced is amd64, right?

[migrym]

There are use cases where an image needs to be created but no compilation is required. In such cases there is no need to cross-compile since everything is already built. For example a base image or tar provides the basic application and any extra dependencies can be added from alpine packages.

Additionally, it seems no command line option is required if the yaml setting build.crossCompile.enabled is meant for that purpose. The setting is currently unused.

#44 You face this issue when building aarch64 under Apple Silicon, which is already linux/armv8.
