The arm64 base image does not have the cross-build command in the Aarc64 architecture.

[iamkhalidbashir]

As mentioned in the title, the Golang cross-build base debian 12 image does not have the cross-build command in the arm64 architecture, but in the x86-64 architecture. This does not get executed correctly on an ARM 64 runtime of Docker and throws an execution format error.

@dliappis I think we fixed this already, but I can't pick out exactly at which point in the commit history. https://github.com/elastic/golang-crossbuild/commits/main/

Is this fixed already or is this still in progress?

[dliappis]

@cmacknz so far the docker.elastic.co/beats-dev/golang-crossbuild:1.24.0-base-debian9 is correct.

There are open PRs to fix the debian11 and other variants too

[iamkhalidbashir]

I cant use debian9 because the repos are archived and have other issues
Cant the PR be merged ?
