This patch is nonsense and needs to be shot down. Do not confuse Cygwin
and MSYS, they are not interchangeable. Use --host to set the cross
compiler triplet instead.

You also run the risk of breaking non-gcc compilers.

Moreover,  *-*-mingw64 does not exist save for a short experimentation
period. It should really be removed. The __MINGW64__ macro on the other
hand is unrelated to any of this.
