Comment:
I attempted removing the custom do_build() and do_install() functions, however builds fail with the error:

```
=> ERROR: docker-cli-20.10.5_1: do_build: 'go get -p "$XBPS_MAKEJOBS" -x -tags "${go_build_tags}" -ldflags "${go_ldflags}" ${go_package}' exited with 1
=> ERROR:   in do_build() at common/build-style/go.sh:39
```

when this is set. I don't know how to fix this, so I'm going to leave the custom functions in, as they compile just fine and I don't see how they could impact build performance if they are similar to the default. Feel free to tell me what the issue is here, as I don't have enough experience with the xbps build system to understand it at 2am.
