Go1.15 deprecates 32-bit macOS builds

https://golang.org/doc/go1.15#darwin

Currently gox still tries to build it, which fails: https://github.com/Mic92/nix-build-uncached/pull/16/checks?check_run_id=1033209325#step:6:32

Yep, seen this too with:

1 errors occurred:
--
44 | --> darwin/386 error: exit status 2
45 | Stderr: cmd/go: unsupported GOOS/GOARCH pair darwin/386

Hello,

Any solution for this?

Thanks.

[Matthias Loibl]

I looked at the solution done in the repo linked above by @Mic92.
Here's the fix for me: metalmatze/digitalocean_exporter@60ab0b6
Essentially building everything except darwin/386.

I blacklisted it in my github action as well.
