	* elf/Makefile (LDFLAGS-nodelete): Add -rdynamic.
	* elf/nodelete.c (fini_ran): New global variable.
	(do_test): Before every dlclose call clear fini_ran and test
	afterwards that it is not set by the destructors.
	* elf/nodelmod1.c: Add destructor which sets fini_ran.
	* elf/nodelmod2.c: Likewise.
	* elf/nodelmod4.c: Likewise.
