<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 for a 32-bit Intel machine will be

A sure-fire way to determine the name of the dynamic linker is to
inspect a random binary from the host system by running:
<userinput>readelf -l &lt;name of binary&gt; | grep interpreter</userinput>
