     <para>Also be aware of the name of the platform's dynamic linker, often
     referred to as the dynamic loader (not to be confused with the standard
     linker <command>ld</command> that is part of Binutils). The dynamic linker
     provided by Glibc finds and loads the shared libraries needed by a program,
     prepares the program to run, and then runs it. The name of the dynamic
-    linker will usually be <filename class="libraryfile">ld-linux.so.2</filename>.
-    On platforms that are less prevalent, the name might be <filename
-    class="libraryfile">ld.so.1</filename>, and newer 64 bit platforms might
-    be named something else entirely. The name of the platform's dynamic linker
-    can be determined by looking in the <filename class="directory">/lib</filename>
