The motivation is indeed that right now that CROSS= argument specifies a 
compiler prefix that doesn't exist.

I've just tested in an Ubuntu Docker container and it does seem that the 
LE compiler can do BE fine as long as that CROSS= argument is changed, 
though if we want to do that I should probably add a note clarifying 
that yes, skiboot is still BE.

(It also turns out that we need to add xz-utils to the package list... 
anyone know what the xz package name is on Fedora?)
