Either the configure script does not handle the target triple
x86_64-pc-mingw64 correctly, or that target triple is incorrect (IIRC
the target triple is inferred by a script `configure' calls:
build-aux/config.guess.)

I don't build Emacs 64 bits on Windows, just the 32 bit build (as the OP
does). It works fine without passing any parameter to `configure'.
