Build documentation should explain that building on WSL is not possible

Per:

https://stackoverflow.com/questions/47531475/launch-vscode-from-source-through-wsl

both I and "taylorstine" had the same experience when building vscode from source in WSL. We got past the dependency installation challenge to find that when we ran ./scripts/code.sh that something was clearly running (i.e. was persistent in the process table) but the GUI never materialized. Both of us had an X server up and running that was able to "catch" other X apps and display them (xeyes, in my case).

Could we update the Wiki to clearly state that WSL is not a build platform at present? I have updated the Wiki to reflect this reality: microsoft/vscode-wiki#40.

Yes, we know. The corresponding WSL issue is: microsoft/WSL#2293

Thank you for the reference to that issue. Foremost it was a wonderful description of debugging a hard problem that, frankly, ought be included in most programming education. Thanks, as well for the additional context. From the VSCode perspective, it looks like the VSCode docs should say that WSL is not a build target until microsoft/WSL#2293 is resolved.

Done.
