Problems with building GHC 7.8.3 on Windows

[Austin Seipp]

Thanks for the input Marek. I kept the pages separate at first because
it wasn't clear if we wanted to buy into MSYS2 - hence why it's on a
separate page.

I think it's proven itself enough that we can now move the pages
around - making the current page a 'legacy only' page, and moving the
MSYS2 docs to the forefront.
