I have changed an easier way.
During chapter 5, I change the call to execute makefile adding
SHELL='/bin/bash'
For reference, this does not only fix the expansion trouble in the scripts
but fix too gcc-4.2.3 compilation on Ubuntu-8.04.
The error was with bash shell :
In file included from ./tm.h:15,
from
/scratch/joseph/4.2.3/gcc-4.2.3/gcc-4.2.3/gcc/gengtype-yacc.y:26:

../../gcc-4.2.3/gcc/gengtype.h:100: error: field 'line' has incomplete type
make[4]: *** [build/gengtype-yacc.o] Error 1
Another side effect for LFS-5.1 is that this time adding SHELL='/bin/bash'
during chapter 5 break gcc-3.3.3 compilation during installation.
Error was
/bin/bash ../libtool --mode=install /bin/bash
/home/gesp/ipcop/1.4b/build/usr/src/gcc-3.3.3/install-sh -c libsupc++.la
/tools/lib/./libsupc++.la
libtool: install: `/tools/lib/./libsupc++.la' is not a directory
During gcc installation, I had to force /bin/sh usage with
make $(EXTRA_INSTALL) SHELL=/bin/sh install
