Implemented in the first one of the attached patches.  The second patch
is a follow-up updating the "maintainer-check" rules accordingly.

OK for maint?  This should be quite uncontroversial, so I'll push in 72
hours if there is no review by then.

Regards,
  Stefano

Subject: [PATCH 1/2] distcheck: add support for AM_DISTCHECK_CONFIGURE_FLAGS

* doc/automake.texi (Checking the Distribution): Suggest to use
AM_DISTCHECK_CONFIGURE_FLAGS, not DISTCHECK_CONFIGURE_FLAGS, to
define (in the top-level Makefile.am) extra flags to be passed
to configure at "make distcheck" time; DISTCHECK_CONFIGURE_FLAGS
should be reserved for the user.  Add proper address@hidden' directive.
Document that AM_DISTCHECK_CONFIGURE_FLAGS is not honoured in a
subpackage Makefile.am, but the flags in it are passed down to
the configure script of the subpackage.
* lib/am/distdir.am (distcheck): Also pass the flags in
$(AM_DISTCHECK_CONFIGURE_FLAGS) to the configure invocation.
Update comments.
* tests/defs.in.test (AM_DISTCHECK_CONFIGURE_FLAGS,
DISTCHECK_CONFIGURE_FLAGS): Unset in case they are exported in
the environment, they might improperly influence our testsuite.
* tests/distcheck-configure-flags.test: New test.
* tests/distcheck-configure-flags-am.test: Likewise.
* tests/distcheck-configure-flags-subpkg.test: Likewise.
* distcheck-hook.test: Likewise.
* distcheck-hook2.test: Likewise.
* tests/Makefile.am (TESTS): Update.

Closes automake bug#8487.

Subject: [PATCH 2/2] maintcheck: DISTCHECK_CONFIGURE_FLAGS can be defined on 
make cmdline

* Makefile.am (sc_tests_overriding_macros_on_cmdline): It's now
acceptable that the test scripts override DISTCHECK_CONFIGURE_FLAGS
on the make command line.  Update comments accordingly.  Since we
are at it, make the relevant grepping rules slightly tighter.
