Configure: gcc problem under mingw/i386

[Austin Seipp]

Please update your GHC repository tree, then run:

./sync-all get

There was a bug I fixed today where 'msys' wasn't correctly detected as
Windows, so it skipped the ghc-tarballs repository.

Then make sure you do './sync-all pull' to update everything else (there
were other changes that require syncing.)

Hopefully that helps.
