AFAIK, the reason is to be able to build multiple bootwrapper
configurations around a single kernel image without multiple compiles of
the wrapper bits, and to increase the amount of compile testing that all
the wrapper bits are subjected to.  (this way they get compiled on all
PowerPC kernel compiles instead of just when they are needed for an
obscure platform)
