docs: it's not true that DISTCHECK_CONFIGURE_FLAGS is maintainer-reserved At least, not anymore since commit 'v1.11-372-g9760039' of 2001-06-10, "distcheck: add support for AM_DISTCHECK_CONFIGURE_FLAGS". See also automake bug#8784. * doc/automake.texi (Flag Variables Ordering): Do not report 'DISTCHECK_CONFIGURE_FLAGS' as a "variables that are only useful to the maintainer that has no user counterpart": now it is a user-reserved variable, its maintainer-reserved counterpart being 'AM_DISTCHECK_CONFIGURE_FLAGS' .
