use libiberty xmalloc in bfd/doc/chew.c

Catch out of memory.

	* doc/chew.c: Include libibery.h.
	(init_string_with_size, nextword): Replace malloc with xmalloc.
	(newentry, add_to_definition): Likewise.
	(catchar, catbuf): Replace realloc with xrealloc.
	(add_intrinsic): Replace strdup with xstrdup.
	* doc/local.mk (LIBIBERTY): Define.
	(chew): Link against libiberty.
	* Makefile.in: Regenerate.
