[Automake-ng] [PATCH 00/10] Rewrite parallel-tests to rely on GNU make capabilities

[Stefano Lattarini]

A patch series that rewrites step-by-step a substantial part of the parallel
testsuite harness, to make it take advantage of more GNU make features.
It accomplishes this by moving some of the processing from automake runtime
to make runtime.  And in doing so, it also offers a good example of the
general improvements and enhanced semantics Automake-NG can offer.

The sixth and seventh patches are not part of the series proper, but start
making use of the new features the rewrite offers in Automake's own
testsuite, and thus also serve as a useful showcase of the advantages these
features can bring.

The last two patches fixes some minor fallout, which was small enough not
to warrant further rebasing and tweaking of an already much-rewritten series.

I will push in 72 hours.  Reviews welcome.

Regards,
  Stefano

  [01] parallel-tests: simplify, using pattern rules with multiple targets
  [02] cleanup: simplify %transforms for parallel-tests handling
  [03] parallel-tests: simplify automake-time preprocessing
  [04] coverage: parallel-tests and dynamic $(TESTS) content
  [05] parallel-tests: support "TESTS = $(srcdir)/foo.test"
  [06] build: define $(TESTS) through a wildcard
