  20   20  # to the proto area with the new version of libld.so.4. One thing that we have
  21   21  # to do is be careful with using LD_LIBRARY_PATH. Setting LD_LIBRARY_PATH does
  22   22  # not change the default search path so we want to make sure that we use a
  23   23  # different ISA (e.g. 32-bit vs 64-bit) from the binary we're generating.
