You have several possibilities to set the $LFS variable:
If you don't have the file /root/.bashrc you can create it by typing 
# touch ~/.bashrc
After this you have to add the line
export LFS=/path/to/lfs
to this file.
Instead of creating the .bashrc you can also add the export command to the
file ~/.bash_profile
I don't know the difference exactly, but it should work, too.
On suse systems you can export variables by putting them as above in
/etc/profile.local . In this case the variables are known to all users on the
Just try it!
