Not quite, and the difference can be seen when you look at the link
*outside* the chroot environment (i.e where the filesystem is mounted
to /mnt/lfs).

The /lib directory becomes /mnt/lfs/lib, and so the first link now
expands to /mnt/lfs/usr/bin/cpp. However, the second link is an absolute
path, and so still points to /usr/bin/cpp - not to the file it was
intended to point at.

Simon.
