    deps: fix corner-case "make distclean" bug
    
    Assume we have package satisfying the following conditions:
      (1) automatic dependency tracking is enabled;
      (2) the 'subdir-objects' Automake option is enabled;
      (3) the package uses a recursive make setup.
    
    Also assume that:
      (a) a subdir Makefile declares a foo_SOURCES variable containing
          a source file in the parent directory;
      (b) that parent Makefile declare a compiled program itself.
    
    Then BSD and Solaris make used to fail when running "make distclean",
    because the 'distclean' target of the subdir Makefile removed the
    whole '.deps' directory before the parent Makefile was done with the
    included '.Po' makefile fragments in that directory. This issue was
    revealed by failures in the 'subobj-vpath-pr13928.sh' test when those
    make implementations were used.
    
    We fix the issue by ensuring the 'distclean' target of any Makefile
    only removed the '.Po' makefile fragments included by it, rather than
    the whole '.deps' directory where such files resides.
    
    This change should be the last step in fixing automake bug#13928
    for good.
    
    * bin/automake.in (handle_languages), lib/am/depend.am: Adjust
    to implement the new 'distclean' logic.
    * t/pr224.sh: Adjust to avoid a spurious failure.
    * PLANS/subdir-objects.txt: Update.

    compile: don't place built object files in $(srcdir), ever ...
    
    ... even when a source file is specified as '$(srdir)/foo.c' or
    '$(top_srcdir)/bar.c'. And ditto for dependency-tracking makefile
    fragments (those under '.deps' directories).
    
    Such issues used to occur when the 'subdir-objects' option was given.
    
    This change should fix the second and last part of automake bug#13928.
    See also bug#16375 and bug#15293.
    
    * NEWS: Update.
    * bin/automake.in (handle_single_transform): Make sure object files
    and dependency-tracking makefile fragments coming from source like
    '$(srcdir)/foo.c' and '$(top_srcdir)/bar.c' are placed respectively
    under $(builddir) and $(top_builddir).
    * t/subobj-vpath-pr13928.sh: Enhance to expose even more aspects
    of the bug we've just fixed.
    * t/subobj-pr13928-more-langs.sh: New test, similar to the one above,
    but with non-C languages as well.
    * t/list-of-tests.mk (XFAIL_TESTS): Remove 'subobj-vpath-pr13928.sh',
    it's now supposed to pass.
    (handwritten_TESTS): Add 'subobj-pr13928-more-langs.sh'.

    tests: fix some bugs in an XFAILing test
    
    * t/subobj-vpath-pr13928.sh: This one. The test would have failed (or
    hung!) even if the bug it was testing against were fixed.

    deps: 'subdir-object' option now works when foo_SOURCES contains $(var)
    
    Following a suggestions of Johan Kristensen, we have config.status use
    'make' invocations rather than Makefile-parsing 'sed' hacks to bootstrap
    the dependency-tracking '.Po' and '.Plo' makefile fragments. To handle
    the inclusion of such files that are still missing when make is first
    we basically generate a temporary Makefile without these includes, and
    call 'make' on that Makefile.
    
    This fixes the serious bug bug#13928, which was an hard blocker to make the
    behavior mandated by the 'subdir-object' active by default (which we want
    to do in Automake 2.0).
    
    The issue has also been reported in bug#15919.
    
    * NEWS, THANKS: Update.
    * bin/automake.in (handle_languages): Add a trailing "marking" comment
    ("# am--include-marker") to the generated Makefile lines issuing 'include'
    directives for the dependency-tracking '.Po' and '.Plo' makefile fragments.
    Also rename the generated Makefile variable 'am__depfiles_maybe' to the
    clearer 'am__maybe_remake_depfiles'.
    Minor unrelated refactoring.
    * lib/am/configure.am: Adjust to account for the 'am__depfiles_maybe' ->
    'am__maybe_remake_depfiles' renaming.
    * lib/am/depend.am: Add rules to generate a dummy version of all the
    dependency-tracking '.Po' and '.Plo' makefile fragments.
    * m4/depout.m4: Use make invocations rather than Makefile-parsing sed hacks
    to bootstrap the dependency-tracking '.Po' and '.Plo' makefile fragments.
    We still use some sed trickery in order to remove the inclusion of the
    still non existing .Po and .Plo files from the Makefile we invoke make
    upon; this is done stripping lines that contain the magic string
    "# am--include-marker".
    * m4/make.m4 (AM_MAKE_INCLUDE): Given that now automake generates Makefiles
    containing include statements with trailing comment, adjust the checks done
    here to make sure $MAKE support that; e.g., "include foo.mk # comment"
    rather than just "include foo.mk".
    Also refactor and adjust to leave better debugging info in config.log.
    * t/postproc.sh: Rename ...
    * t/depend-postproc.sh: ... to this, and adjust and enhance.
    * t/list-of-tests.mk (handwritten_TESTS): Adjust.
    (XFAIL_TESTS): Remove 't/subobj-indir-pr13928.sh', which is now succeeding.
    * t/subobj-indir-pr13928.sh: Simplify slightly, now that we expect it to
    pass.
    * t/depcomp8a.sh: Adjust grepping check to account for the changes in
    the generated Makefile, and tp be somewhat more robust in light of possible
    future modifications.
    * t/depcomp8b.sh: Likewise.
    * t/subobj11b.sh: Likewise.
    * t/subobj11c.sh: Likewise.
    * t/extra-sources.sh: Likewise.
    * t/lex-depend-grep.sh: Likewise.
    * t/lex-depend-cxx.sh: Add a command to help debugging in case of test
    failure.
