Subject: make tests: remove failed .out.

* Makefile (%.ok): If the .out file differs from .expected,
don't just fail this rule. Remove the .out file also, so
that when "make tests" is repeated, the test is re-run to
regenerate it. Otherwise "make tests" will only run diff
again on the previously generated .out file.
