provide non-x86 ebpf-builder

[grooverdan]

I got an error building skydive as the skydive/ebpf-builder image is x86_64 only.

I worked around this with:

ebpf/Makefile
@@ -35,7 +36,7 @@ build-ebpf-docker-image:
 pull-ebpf-docker-image:
        docker pull $(DOCKER_EBPF_BUILDER_IMAGE):latest
 
-docker-ebpf-build: pull-ebpf-docker-image
+docker-ebpf-build: build-ebpf-docker-image
        docker run --rm \
                --env=UID=$(UID) \
                --env=GID=$(GID) \
I'm wondering if there's a way to encode this so non-x86 can work cleaner.

Or make the ebpf-builder image multi-arch?

Daniel, thanks for this. We do need SkyDive for power but the ebpf Makefile always pulls x86 docker image leading to the exec format error on P9/Power. Please see below:

  $ uname -a

Can ebpf-builder multi-arch image be provided for building Skydive for Power.
