[AIX] 16.0.2 release testing - Failing test-suite tests due to textual differences between characters

[nicolerabjohn]

While testing 16.0.2 on an AIX7.2 (power7) machine, I came across these failing tests:

  test-suite :: MultiSource/Applications/spiff/spiff.test
  test-suite :: MultiSource/Benchmarks/NPB-serial/is/is.test

The failures are as follows:

Looking into it now.

Just an environment setup issue.
