enable building of new stdio64 directory.
* libc/Makefile.am[HAVE_STDIO64_DIR]: Add support for
large files.
(stmp-stdio64,stdio64.texi): New targets to optionally add in
stdio64 info to info files.

* libc/configure: Ditto.
* libc/configure.in: Add configuration variables that are set
when stdio64 is selected as subdir in configure.host.
* libc/libc.texinfo: Add optional menu item for Stdio64, based
on whether STDIO64 flag is set or not.
* libc/sys.tex: Add optional stdio64 syscalls based on whether
STDIO64 flag is set or not.
* libc/include/reent.h[__LARGE64_FILES]: Add new stdio64
_r sycall routines.
* libc/include/stdio.h[__LARGE64_FILES]: Add new stdio64 prototypes.
(FILE): Typedef'd to __FILE instead of struct __sFILE directly.
(__SL64): New file flag indicating file is opened via fopen64.
* libc/include/sys/_types.h(_off64_t): Added.

* libc/include/sys/reent.h(struct __sFILE64): New file structure
for 64-bit offset large file support.
(__FILE): New intermediate type either set to struct __sFILE64 or
struct __sFILE, depending on whether __LARGE64_FILES is set or not.
