C99 binutils configury

Browse Source 
* configure.ac: Assume long long is available.  Don't test for
	strings.h, stdlib.h, limits.h, locale.h, or wchar.h.  Check
	inttypes.h, stdint.h, sys/stat.h and sys/types.h. Don't check for
	strcoll, setlocale, setmode or location of time_t.  Don't check
	for fprintf, getenv, snprintf, strnlen, strstr or vsnprintf decls.
	(AC_ISC_POSIX, AXC_HEADER_STRING, AC_FUNC_ALLOCA): Don't invoke.
	* sysdep.h: Don't include alloca-conf.h, include config.h instead.
	Test HAVE_SYS_TYPES_H and reorder includes.  Include limits.h,
	locale.h, string.h and stdlib.h unconditionally.  Remove various
	fallback declarations.  Assume long long is available.
