  Issue::
   In the first phase of chroot terminal is not quite usable (no backspace key etc).
- Solution::
-  remove "--disable-db-install" from the ncurses chap5 configure

+ Solutions::
+  - remove ''--disable-db-install'' from the ncurses chap5 configure. This means that '''tic''' should be present on the host with a suitably recent version (>= 6.0)
+  - build '''tic''' from the ncurses package with build host tools, and use it to compile the terminfo database when cross-building ncurses
+  - build with ''--disable-db-install'' and copy the /usr/share/terminfo database from the build host to the target lfs host (taints target in some way, who knows what is exactly in that database?).
+  - build with ''--disable-db-install'', then run the built '''tic''' to install the terminfo database (taints cross compile, but the most economical)

+ Discussion::
+  There are only warnings, then the error is about a missing file when running the m4 subprocess. To troubleshoot: '''type m4''' and '''ldd /usr/bin/m4''', also try to run bison with a verbose switch.
+
+  For the '''tar''' issue, is it in a pipe? The mailing list thread concluded that it was related to a change in the way the SIGPIPE signal was handled.
