Calico eBPF PPC64 support

[astenmco]

My cluster uses PPC64 nodes (alongside x86-64 nodes).
I wanted to enable eBPF in calico but saw in the docs that only x86-64 and arm64 are supported.

Would you consider adding PPC64 support ?

Thanks for the hard and excellent work !

@astenmco I do not see that happening any time soon, even though essentially the only real problem is that our ebpf platform expects little endian arch. Afaict PPC64 is unfortunately big. And since it is not quite the most common platform out there, our limited resources do not let us prioritize it. Obviously, we would be happy to review and help to push though any community contributed patches from someone who has access to the hardware 🤷‍♂️

@astenmco just making sure -- but you're asking for BE (ppc64) support for Power?
