Merge branch 'maint' into branch-1.11

* maint:
  recheck: fix interaction with "make -n"
  vala: avoid potential useless remakes (minor bugfix)
  vala: enhance tests
  recheck: behave better with non-GNU make
  check: separate .log -> .html conversion from core testsuite harness
  docs: deprecate .log -> .html conversion by parallel-tests
  tests: list some forgotten test cases in $(TESTS)
  maintcheck: consistency of list of test scripts
