Crossbuilt kernel header not useful on the host
dpkg-buildpackage -uc -us -B --host-arch=arm64
make -j4 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- bindeb-pkg
currently produces kernel headers that contain x86 binaries. That together with #265 makes building modules for the
imx8-next-liubrem5 branch more of an adventure than need be. #265 is the more worthwhile fix though since it also helps users. Mostly filing this here so we have a linkeable reference.
