You're building your mingw32 binaries with an i686- compiler,
not an x86_64- one, so you'll end up with 32-bit Windows binaries
running on your 64-bit Windows installation.
If you have the 64-bit cross compiler and libraries for it you
could try a --cross-prefix=x86_64-w64-mingw32- build.
On this end I should try this with a 32-bit Linux host.
