After you have a working cross-compiler, your next step should be to
install an autobuilder. However, many packages use configure scripts. For
them to use a different compiler all that is necessary is to set
CC=cross-gcc and the package will be produced for the correct
architecture. I know it works because I have used it many times. The
problem is the packages which are more hardcoded (no standard makefiles,
etc.). But in the end you end up creating a new distro. Wrt this matter,
I thought the kernel provided some sort of compatibility between
PPC60x/7xx <-> MPC860 chips?
