You can't do it with 4.x .h-files. You need to use 5-CURRENT
headers. The cross-tools phase, stage 3, uses the host system's
headers.

It builds fine on 4.x as long as you use the correct headers. It
appears to run fine on 4.x too. It's just that you pretty much need to
add a new stage to the build process. A stage where one builds
cross-tools with the new header files.
