+          <para>By default, the linker would generate both the GNU-style
+          hash table and the classic ELF hash table for shared libraries and
+          dynamically linked executables.  The hash tables are only intended
+          for a dynamic linker to perform symbol lookup.  On LFS the dynamic
+          linker (provided by the Glibc package) will always use the
+          GNU-style hash table which is faster to query.  So the classic
+          ELF hash table is completely useless.  This makes the the linker
+          only generate the GNU-style hash table by default, so we can avoid
+          wasting time to generate the classic ELF hash table when we build
+          the packages, or wasting disk space to store it.</para>
