go117.base64 is a base64-encoded Go 1.17 hello world binary used to test debug/buildinfo of pre-1.18 buildinfo encoding.
The binary is base64 encoded to hide it from security scanners that believe a Go 1.17 is inherently insecure.
Generate go117.base64 with:
$ GOTOOLCHAIN=go1.17 GOOS=linux GOARCH=amd64 go build -trimpath $ base64 go117 > go117.base64 $ rm go117
TODO(prattmic): Ideally this would be built on the fly to better cover all executable formats, but then we need a network connection to download an old Go toolchain.
