Bug 1417684 - Stop looking for mingw32-make; r?build Support for mingw32-make was added in bug 1100925 in order to support msys2. That project is effectively dead. I'm about to refactor this code and don't want to deal with extra requirements. So delete references to mingw32-make. MozReview-Commit-ID: FMl4OzpLHwv
