Directory lookup is needed regardless, and #ifdefing away symlink
support sounds reasonable to me: dont use symlinks to 2nd-stage
bootblocsk (installboot could check for that).  Is the problem that
the Alpha LFS bootblock was already so close to the edge of the cliff,
that looking into a /boot directory directory leaves it teetering on
the edge?
