  18 # This test validates that the -zassert-deflib option of ld(1) works correctly.
  19 # It requires that some cc is in your path and that you have passed in the path
  20 # to the proto area with the new version of libld.so.4. One thing that we have
  21 # to do is be careful with using LD_LIBRARY_PATH. Setting LD_LIBRARY_PATH does
  22 # not change the default search path so we want to make sure that we use a
  23 # different ISA (e.g. 32-bit vs 64-bit) from the binary we're generating.
