  Makefile: enable target overridings. (#661) This patch allows target to provide extra files enabling the override of Makefile rules. This patch is not needed for libffi itself but only for GCC on AIX. The t-aix file which is here empty will be replaced in GCC repository. We cannot include GCC version directly here because it has no sense for a standalone libffi. Co-authored-by: Clement <clement.chigot@atos.net>
