remove "+h" in bash commands in chroot (#4998)

In the new cross-compilation approach, the $PATH in chroot does not
contain '/tools/bin'. So "+h" is useless in chroot as the newly
installed tools always replace the temporary counterpart at the same

"+h" in chapter4/settingenviron.xml is kept deliberately. Currently
$LFS/tools/bin only contains programs prefixed with
"x86_64-lfs-linux-gnu-", and it's highly unlikely that any distro will
ever ship a program named with such prefix. So it may seems that we can
remove this "+h" as well. However, the situation may change in future
and we can take this oppertunity to teach the advantage and disvantage
of bash hash feature.

11 <title>Cleaning Up</title>
13 <para>Finally, clean up some extra files left around from running tests:</para>
15<screen><userinput>rm -rf /tmp/*</userinput></screen>
17 <para>There are also several files installed in the /usr/lib and /usr/libexec
18 directories with a file name extension of .la. These are "libtool archive"
19 files. As already said, they are only useful when linking with static
20 libraries. They are unneeded, and potentially harmful, when using dynamic
21 shared libraries, specially when using also non-autotools build systems.
22 To remove them, run:</para>
24<screen><userinput>find /usr/lib /usr/libexec -name \*.la -delete</userinput></screen>
26 <para>For more information about libtool archive files, see the <ulink
27 url="&blfs-book;introduction/la-files.html">BLFS section "About Libtool
28 Archive (.la) files"</ulink>.</para>
30 <para>The compiler built in <xref linkend="chapter-temporary-tools"/> and
31 <xref linkend="chapter-chroot-temporary-tools"/> is still partially
32 installed and not needed anymore. Remove it with:</para>
34<screen><userinput>find /usr -depth -name $(uname -m)-lfs-linux-gnu\* | xargs rm -rf</userinput></screen>
36 <para>Finally, remove the temporary 'tester' user account created at the
37 beginning of the previous chapter.</para>
39<screen><userinput>userdel -r tester</userinput></screen>
