      Upgrade GCC to 5.2.0 for Windows x86 and x86_64 · 7b211b4e
      Tamar Christina authored and Ben Gamari's avatar Ben Gamari committed
      This patch does a few things
      
      - Moved GHC x86 to MinGW-w64 (Using Awson's patch)
      - Moves Both GHCs to MSYS2 toolchains
      - Completely removes the dependencies on the git tarball repo
        - Downloads only the required tarball for the architecture for
          which we are building
        - Downloads the perl tarball is missing as well
        - Fixed a few bugs in the linker to fix tests on Windows
      
      The links currently point to repo.msys2.org and GitHub, it might be
      more desirable to mirror them on
      http://downloads.haskell.org/~ghc/mingw/ as with the previous patch
      attempt.
      
      For more details on what the MSYS2 packages I include see #10726
      (Awson's comment). but it should contain all we need
      and no python or fortran, which makes the uncompressed tar a 1-2
      hundreds mb smaller.
      
      The `GCC 5.2.0` in the package supports `libgcc` as a shared library,
      this is a problem since
      when compiling with -shared the produced dll now has a dependency on
      `libgcc_s_sjlj-1.dll`.
      To solve this the flag `-static-libgcc` is now being used for all GCC
      calls on windows.
      
      Test Plan:
      ./validate was ran both on x86 and x86_64 windows and compared against
      the baseline.
      
      A few test were failing due to Ld no longer being noisy. These were
      updated.
      
      The changes to the configure script *should* be validated by the build
      bots for the other platforms before landing
