Thanks Jon. One tiny question tho' (I'm total newbie at this). When do I 
do make DESTDIR? At the stage, make -j 2 bootstrap, in which case the 
command would be make DESTDIR=/transfer/gcc-build-archive -j 2, or at 
the final make install stage? (The latter doesn't work.)

If the former is the case, then I would simply copy 
/transfer/gcc-build-archive to the target machines and run make install 
on each, right?

Also, do I have to install texinfo and ncurses on the target machines?

Thanks.
