Changes since 1.5: +4 -4 lines

Pull up following revision(s) (requested by joerg in ticket #1423):
	lib/libc/stdlib/exit.c: revision 1.12
	lib/libc/misc/initfini.c: revision 1.6
Ensure that initfini.c is referenced by exit.c. The start up code has to
reference the latter as a return of main() results in a call to exit(3),
so this ensures that the libc constructors are run for statically linked
programs. Fixes PR 37454.
