  tests: fix spurious failures with "chatty" make implementations
  
  * tests/distcheck-missing-m4.test: On failure, some make
  implementations (such as Solaris make) print the whole failed
  recipe on standard output.  This was causing a spurious failure
  in the checks grepping the output from make.  Work around this.
  * tests/distcheck-outdated-m4.test: Likewise.
