We will need to copy our BUILD Variables into our new system. So when we boot-up they will be there:

echo export BUILD32=\""${BUILD32}\"" >> ${LFS}/root/.bash_profile
echo export BUILD64=\""${BUILD64}\"" >> ${LFS}/root/.bash_profile
echo export LFS_TARGET32=\""${LFS_TARGET32}\"" >> ${LFS}/root/.bash_profile
