The patch works unmodified (and solves mingw build problems) for gcc 4.9. as
well,
providing gcc-4.9.inc is patched the same way as gcc-5.2.inc
(However, this makes the Makefile.in patch status:
Upstream-Status: Pending
incorrect for case of gcc 4.9.)

> Without this patch, the wrong header fragments can be used to generate the
> nativesdk, cross-canadian, and other variations. Generally this works fine.
> However, when there is enough variation from the build machine to the
> target runtime it will break.. (Such as SDKMACHINE=i686-mingw32)

> The bugs can also how up on a Linux -> Linux build, but it's signficiantly
> more
> rare. It would require some set of options that make the host headers and
> flags incompatible with the target. (Such as various profiling
> options.)
>
> This has been tested with a set of meta-mingw patches that will be sent to
> the Yocto Project mailing list soon.
