Merge #11437: [Docs] Update Windows build instructions for using WSL and Ubuntu 17.04
696ce46 [Docs] Update Windows build instructions for using WSL and Ubuntu 17.04 (fanquake)
4f890ba Add new step to clean $PATH var by removing /mnt specific Window's %PATH% paths that cause issues with the make system (Donal OConnor)
Pull request description:
This updates the Windows build documentation with the workaround required to build using Ubuntu 17.04 on WSL, and makes it's explicit that building on Ubuntu 16.04 is broken, and not recommended.
This includes a commit from @donaloconnor in #11244, and is mostly the investigative work of @laanwj throughout #8732, #8653 and quite a few other issues.
I tested building on 14.04, 16.04.3 and 17.04 [here](https://github.com/bitcoin/bitcoin/pull/11244#issuecomment-327990251) and got the results we expect.

Built master at https://github.com/bitcoin/bitcoin/commit/c22a53cd6351b3f0e96de971b001ad712b83fc47 on a Windows 10 VM (Version 1607, OS Build 14393.1593) using WSL with Ubuntu 14.04.
Upgraded WSL to 16.04.3, and tried building https://github.com/bitcoin/bitcoin/commit/c22a53cd6351b3f0e96de971b001ad712b83fc47 using these instructions. The result is as expected.
Upgraded WSL to 17.04 and tried building https://github.com/bitcoin/bitcoin/commit/3255d6347b1f9eccbec3d6d93d4a424087a3b35b using these instructions.
If someone else could also verify that builds are working on both 14.04 and 17.04 with these instructions, that would be great.
