[yocto] [meta-mingw] gcc 5.2 partial patches

[Peter Seebach]

So I've got patches for meta-mingw which make it fail in an interesting way
instead of in a boring way.

http://git.yoctoproject.org/cgit.cgi/poky-contrib/commit/?h=seebs/gcc52gw

With these, we get past all the obvious not-even-applying, and blow up
because one of the mingw headers complains that it can't be compiled except
for WIN32 targets. Have not further explored yet.

Listen, get this.  Nobody with a good compiler needs to be justified.
