In basic terms, you need a machine which:

* Sets TARGET_ARCH to the right thing (i686 or x86_64)
* Sets TARGET_OS to mingw32

and then some distro config which sets up the toolchain when mingw is
the target os to the values like meta-mingw/conf/machine-sdk/i686-
mingw32.conf sets.

You'd need need to look through the bbappends which are in meta-mingw
and add them to the appropriate pieces you need for target binaries
rather than sdk binaries.

I did once do this for darwin so it is possible, I've never tried it
for windows though.

Cheers,

Richard
