  # This is a disturbing workaround needed for s390x based systems, that
  # for some reason isn't encountered with our other architecture cross
  # builds. When trying to build the libshadow test cases for extconf.rb,
  # the process fails with "/opt/pl-build-tools/bin/s390x-linux-gnu-gcc:
  # error while loading shared libraries: /opt/puppetlabs/puppet/lib/libstdc++.so.6:
  # ELF file data encoding not little-endian". It will also complain in
  # the same way about libgcc. If however we temporarily move these
  # libraries out of the way, extconf.rb and the cross-compile work
  # properly. This needs to be fixed, but I've spent over a week analyzing
  # every possible angle that could cause this, from rbconfig settings to
  # strace logs, and we need to move forward on this platform.
