Building ghc on Windows with msys2

[Thomas Miedema]

Hello msys2 users,

I came across ticket #8842 <https://ghc.haskell.org/trac/ghc/ticket/8842>:
"Make sure msys2 builds non emulating binaries". Maybe it is of interest to
you, it mentions something about emulation functions being really slow.
Please close it if it is not relevant.

Cheers,
Thomas
