[go] missing go.env

[AeliusSaionji]

Description / Steps to reproduce the issue

On first install, the go environment variables are not all populated. In particular, GOPROXY is empty and this prevents downloading dependencies.

It appears a recent change in go expects a go.env in GOROOT?

archlinux appears to be inlcuding this file, https://gitlab.archlinux.org/archlinux/packaging/packages/go/-/commit/97e19acbc78f2b2a19f6ed25aee510669d70fc65 (thanks biswa96)

Reproduce build failures by...

1. go clear -cache -modcache
2. try to build something with a remote dependency.

Expected behavior

Go environment populated with whatever defaults required to build packages.

Actual behavior

Attempts to build packages fail as remote dependencies cannot be downloaded

Building android-tools fails:

  [184/488] Generating err_data.c
  FAILED: vendor/boringssl/crypto/err_data.c C:/_/B/src/build-CLANG64/vendor/boringssl/crypto/err_data.c 
  cmd.exe /C "cd /D C:\_\B\src\android-tools-33.0.3p2\vendor\boringssl\crypto\err && C:\msys64\clang64\bin\go.exe run err_data_generate.go > C:/_/B/src/build-CLANG64/vendor/boringssl/crypto/err_data.c"
  go: golang.org/x/[email protected]: GOPROXY list is not the empty string, but contains no entries

I think the only thing that changed since latest successful build is "go: Update to 1.21.0"
