Message:

shadow: get rid of /bin and /sbin from $PATH

This will be the default system-wide setting of LFS. However, it will
be free to reset $PATH in .bashrc, so we can't assume everyone will use
this. We still need to find and fix breakages caused by hardcoded
paths to /bin/some_executable in BLFS packages.
