[Buildroot] [PATCH] package/sdl_mixer: fix build after aclocal include revamp

After d255b67972 (autotools: do not overwrite first include path), the
ordering of include paths has changed: the system directories are
specified with explicit options passed to autoreconf, which means that
any directory specified in the package _AUTORECONF_OPTS are no longer

  - in package/autoconf/autoconf.mk, we define AUTORECONF as:
    AUTOCONF = $(HOST_DIR)/bin/autoconf -I "$(ACLOCAL_DIR)" -I "$(ACLOCAL_HOST_DIR)"

  - in package/pkg-autotools.mk, we call AUTORECONF with:

So, the include directory specified by SDL_MIXER_AUTORECONF_OPTS is now
lagging behind the system headers, and the very issue that d255b67972
was suposed to fix in a generic way, pops up back for this specific

We fix that by patching sdl_mixer so that it uses the bog-down standard
mechanisms, to specify the macro directory from within configure.in,
instead of specifying it on the command line, so that the magic
introduced by d255b67972 does happen.

+configure: set macro directory
+Setting the macro directory in configure.in, rather than sepcifying it
+on the command line, ensures that it is properly searched in the correct
+order, and that autoreconf properly updates our macros with the newer
+system ones, if any.

+    libtool: Version mismatch error.  This is libtool 2.4.6, but the
+    libtool: definition of this LT_INIT comes from libtool 2.2.6.
+    libtool: You should recreate aclocal.m4 with macros from libtool 2.4.6
+    libtool: and run autoconf again.
