Make repository's packages build on Windows 10

The changes proposed in this pull request allow the respository's packages to be built on Windows 10 version 2004, with:

`stack --resolver nightly-2020-07-24 build --flag hmatrix:openblas`

See the discussion, including about the use of MSYS2 packages and import libraries, at: haskell-numerics#236

The `.gitignore` file is also updated to exclude `.stack-work`.
