[PATCH] Fix nscd build on ia64

[Jakub Jelinek]

Hi!

__libc_alloca_cutoff is only defined in libc.so.  After the latest changes
to check_pf.c nscd fails to link on ia64, because it is not defined.
For nscd we know the stack size (at least for non-initial threads) and
limiting alloca to __MAX_ALLOCA_CUTOFF is ok.

	* nscd/gai.c: Include alloca.h.
	(__libc_use_alloca): Define.
