Tests should not use assert because it writes the message to standard
error, not standard output, where it is captured.  We can add a
different macro to test-skeleton.c for this purpose.  It would be useful
in many cases.

This seems okay.

This one is not related to NDEBUG, I think, but to --with-cpu.
