I see those are also a little out-of-date (at least if you want to use newer GCC), so I should mention that modern mainline LFS also does cross-compiling -- the instructions assume that the host and target are the same architecture, but it's cross-compiling anyway, and with very minor adjustments to the stage2 target string the same system should work for a different host and target.

I haven't recently tried an x86 to PPC build, but I build LFS all the time, and I've tried a couple of 64-bit -> 32-bit cross-compiles, so if you need help let me know.
