`BuildArch: noarch` on -devel only packages

[Maxwell G]

Hi everyone,

I have a quick question: is there a reason that we don't add `BuildArch: noarch` to source only go packages? To be clear, the `-devel` subpackages themselves have `BuildArch: noarch`, but the main packages don't. Unless I'm missing something, Koji still seems to create separate build jobs for each architecture.

Thanks,
Maxwell
