You should probably ask the developers this one, as unless the new 
version says otherwise, it's still a matter of taste and knowing what 
you're doing. Perhaps on some systems it would wreck them royally to use 
the new compiler instead of the host compiler.

The email list for developers should be something like 
lfs-dev at linuxfromscratch.org. I'd check on the site first, though, as 
you still have to subscribe to it.
