    Merge branch 'master' into ng/master

    Noe that, with this merge, we just discarde the changes done to
    the maintainer rules in Makefile.am on the 'ng/master' branch;
    now that the 'maint.mk' file from the 'master' branch assumes
    GNU make as well, those changes have been either rendered obsolete,
    or backported (or planned to be) in the master version of
    'maint.mk'.

    * master:
      sync: update files from upstream with "make fetch"
      gitignore: align with recent changes
      fixup: add dummy rule for ChangeLog generation in Makefile.am
      maint: no longer use AM_MAKEFLAGS in maintainer rules
      maint: use more GNU make features in maintainer rules
      maint: move maintainer make rules in maint.mk
