CentOS and Fedora use ARM64 hardware to do their builds. I think at one
point it was being done with emulation but it was slower than expected..
[if you have only one thing it is probably not a large issue but if you
have a chain of items to build continuously...] For hardware that works
well in an 'enterprise' environment, I can recommend the Ampere systems
that we are using in Fedora.
