Arm v5 fails to build

[KEINOS]

$ build-app -a
...

The path is absolutely wrong.

$ build-app arm 5
fatal: No names found, cannot describe anything.

It won't work. You are missing the GOOS such as "linux".

- $ build-app arm 5
+ $ build-app linux arm 5

[KEINOS]

I will add a message that probably "linux" is missing if the error msg includes "unsupported GOOS/GOARCH pair".
