Subject: Re: use libiberty xmalloc in bfd/doc/chew.c

We can't use libiberty.a in chew.  libiberty is a host library, chew
a build program.  Partly revert commit 7273d78f3f7a, instead define
local versions of the libiberty functions.  ansidecl.h also isn't
needed.

	* doc/chew.c: Don't include libiberty.h or ansidecl.h.
	(xmalloc, xrealloc, xstrdup): New functions.
	* doc/local.mk (LIBIBERTY): Don't define or use.
	* Makefile.in: Regenerate.
