[CentOS-devel] [CBS] aarch64 & existing builds

Hi,

I'd like to add aarch64 builds to existing builds (which were so far
x86_64-only).

So far, I see two solutions:
* scratch-build the same NVR on aarch64 then attach it to the existing
build (mentioned by Jim),
* bumping the release, so that leveldb-1.12.0-5.el7 becomes
leveldb-1.12.0-5.1.el7 - I'd rather not do that as this breaks keeping
in sync with EPEL.

Thomas, Brian, is the first solution feasible, and if yes, can you
detail the steps?

Thanks
François
