Describe the bug

A clear and concise description of what the bug.
Even if I define "go.delveConfig.output" setting (given this documentation), the binary (.exe) generated by delve is still in my "main.go" directory (instead of "C:\Temp").

A clear and concise description of what you expected to happen.
I expect that binary generated by delve (ex: __debug_bin4271654450.exe) is generated in "C:\Temp" directory, and not in my "main.go" directory.

Steps to reproduce the behavior:

1. Put this into vscode "settings.json":

{
    "go.delveConfig": {
        "output": "C:\\Temp"
    }
}

2. Open a "main.go" file
3. Click on 'Run' menu, then "Run Without Debugging"
4. See that "__debug_bin.exe" is generated into "main.go" directory, (instead of "C:\Temp")

Based on my investigation on this issue, I believe this is WAI. But we can consider making it feature request to make it available as well.

• The vscode-go wiki stated that only configuration debugAdapter showGlobalVariables substitutePath is accepted by the go.DelveConfig. So if you want to set this configuration, you can do it by setting in launch.json. Follow instructions in wiki.
• I realized that the output configuration supported by dlv is the file path to the executable, but the example you provided is a directory. The dlv will try to delete the file specified by the output, create the executable and delete the executable afterwards. So instead, you can try "output": "C:\\Temp\debugee".
• If you want to set the set the output debugee in a folder, please consider file a FR to https://github.com/go-delve/delve.

We can turn this into a FR if delve support writing debugee to folder.

Note: if you decided to add the output in launch.json, the configuration will not be picked up when you choose to run a debug session without the launch configuration. See wiki

Timed out in state WaitingForInfo. Closing.

(I am just a bot, though. Please speak up if this is a mistake or you have the requested information.)
