[GNC-dev] Bootstrap Win10 Build Environment

[flywire]

1) Should maintain one set of instructions - wiki should refer to the
readme.

2) The command setup-mingw64.ps1 was not found, but does exist in the
current location. Windows PowerShell does not load commands from the
current location by default. If you trust this command, instead type:
".\setup-mingw64.ps1".

3) Not sure how to set 64-bit

4)  Don't know what this is about after running set-executionpolicy
-executionpolicy RemoteSigned -scope LocalMachine

PS E:\> .\setup-mingw64.ps1 -target_dir: e:\gcde64 -x86_64: set
.\setup-mingw64.ps1 : File E:\setup-mingw64.ps1 cannot be loaded. The file
