Strange line in ltconfig

[H. J. Lu]

In ltconfig, there are

    if test "X$HPUX_IA64_MODE" = X32; then
      sys_lib_search_path_spec="/usr/lib/hpux32 /usr/local/lib/hpux32/usr/local/lib"
    else
      sys_lib_search_path_spec="/usr/lib/hpux64 /usr/local/lib/hpux64"
    fi
 
What is /usr/local/lib/hpux32/usr/local/lib?
