The classic way to do this is to request a macro like
`%{blueprint_arches}` which can be passed to any package requiring the
blueprint compiler. We have several interpreted languages that do
this, if the interpreter isn't available on all arches.
```
$ rpm --showrc|grep _arches

exclusive_arches = "%{golang_arches}"

print(rpm.expand("ExclusiveArch: " .. exclusive_arches .. "\n"))

```
When relying on e.g. Node.js, one is expected to do:
ExclusiveArch: %{nodejs_arches}
