Remove libtool archive (.la) files in Chapter 5 and 6

They are really harmful. In Binutils pass 2, libstdc++.la caused the
building system to use host /usr/lib/libstdc++.so for gprofng. We now
has disabled gprofng for pass 2, but the similar issue also exists in
GCC pass 2. In a normal LFS build, the building system silently uses
/usr/lib/libstdc++.so (I guess it does not blow up simply because some
blind luck); in a real cross build (x86 -> ARM for example) the build
will fail.

Remove the .la files to fix this issue. Instead of only modifying
clfs-ng, it makes more sense to apply the change for trunk: though
the build does not fail, using host library is still a contamination.
