Make sure you specify --sysroot=xxxx where xxxx is the location of
target sysroot you want to compile against.

It is used on Linux to help with these kinds of issues, it will be
completely useless on windows and we shouldn't ship it there.

I've shared the result of my tweaks as
http://git.yoctoproject.org/cgit.cgi/meta-mingw/ btw. I flattened the
history as I had a ton of now meaningless commits and tests so it made
sense for a clean start IMO.
