How can I enable the linker debug output?

To enable some debug information output about the dynamic linker the LD_DEBUG environment variable must be set as follows:

export LD_DEBUG=<option>

 <option> can be set to:

      libs        display library search paths
      reloc       display relocation processing
      files       display progress for input file
      symbols     display symbol table processing
      bindings    display information about symbol binding
      versions    display version dependencies
      all         all previous options combined
      statistics  display relocation statistics
      unused      determined unused DSOs
      help        display this help message and exit

To direct the debugging output into a file instead of standard output a filename can be specified using the LD_DEBUG_OUTPUT environment variable.
