First, I strongly advise to use current version of LFS Book (9.0 as of time of writing). Version 7.7 you use is almost 5 years old now.

Second, your host system (Ubuntu) does not meet LFS requirements:

  1. /bin/sh should be a link to /bin/bash. In your case, it's linked to /bin/dash. Simple fix would be to manually change it. As root:
rm /bin/sh
ln -sv /bin/bash /bin/sh
  1. Your host system uses EGLIBC instead of GLIBC. EGLIBC was designed for embedded devices, attempting to be compatible with standard glibc, and it's discontinued since beginning of 2014 https://en.wikipedia.org/wiki/Embedded_GLIBC. Unfortunatelly I have no idea if it's possible to change EGLIBC to GLIBC on Ubuntu (installing glibc and then removing eglibc could work).
