[PATCH] gcc.c: new macro POST_LINK_SPECS to be able to add additional

steps after linking

	* gcc.c (POST_LINK_SPEC): Define if not already defined.
	(LINK_COMMAND_SPEC): Use post_link.
	(post_link_spec): New, initialize to POST_LINK_SPEC.
	(post_link): Initialize new static spec.
	* doc/tm.texi.in (POST_LINK_SPEC): Document.
	* doc/tm.texi: Regenerated.
