I didn't know we could do that ;-)
And it's even documented.
Thanks!
Then, to enable maint.mk to rely on a definition of $(CONFIG_HEADER)
we could add something like the above to modules/maintainer-makefile:
configure.ac:
AC_CONFIG_COMMANDS_PRE([m4_ifdef([AH_HEADER],
[AC_SUBST([CONFIG_HEADER], m4_defn([AH_HEADER]))])])
