ppc64le support

[clifford2]

Hi guys,

Great tool, thanks for making it available!

I make use of this on ppc64le systems, building it from source for each new release, and sharing a container version of it at docker.io/cliffordw/migrate.

Are there any other users with this need, and if so, is there any appetite for including such a build in the CI? I'll gladly write the code for such a PR if there is.

Kind regards,

Clifford
