* include/alloca.h (stackinfo_alloca_round): Define.
(extend_alloca): Use it.
[_STACK_GROWS_UP]: Correct check for adjacent allocation.
* elf/dl-deps.c (_dl_map_object_deps): Don't round alloca size
here.
* scripts/check-local-headers.sh: Ignore libaudit.h.
* nscd/Makefile (extra-objs): Make recursively expanded.
