  # Test and fix architecture string on AIX
  # On AIX 'config.guess' returns 'powerpc' as architecture but 'powerpc' is
  # implicitely handled as 32-bit architecture in 'platform.m4' so we check
  # for the kernel mode rewrite it to 'powerpc64' if we'Re running in 64-bit mode.
  # The check could also be done with `/usr/sbin/prtconf | grep "Kernel Type" | grep "64-bit"`
