The way you cross-build 4.x release on 5.x/6.x is by installing
the 5.x/6.x world into ${CHROOTDIR}, and using that to cross-
build the 4.x world and kernel, and other bits specific to
"make release". And yes, on a 5.x system, you want to use the
5.x tools to build file system images, including using the md(4)
and mdconfig(8) (5.x kernel doesn't have vn(4)).
