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
location.
"+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.
