When you add a flag somewhere in configure.in and need to use it in code or in the build system, you use AC_SUBST or AC_DEFINE. While using AC_DEFINE in configure.in is usually sufficient for its purpose, using AC_SUBST requires to add some boilerplate in config/autoconf.mk.in, in the form:

VARIABLE_NAME = @VARIABLE_NAME@

Here's the news for you: these days are over. With bug 742795, now on mozilla-central, autoconf.mk is auto-generated. No need to touch config/autoconf.mk.in anymore.
