Allow [f]statfs64 to alias [f]statfs

Browse Source 
* sysdeps/unix/sysv/linux/fstatfs64.c: Hide prototypes for fstatfs
	and __fstatfs.  Make them aliases of __fstatfs64 if
	STATFS_IS_STATFS64 is set to non-zero.
	* sysdeps/unix/sysv/linux/statfs64.c: Ditto for __statfs, statfs,
	and __statfs64.
	* sysdeps/unix/sysv/linux/generic/wordsize-32/fstatfs.c: Do not
	define __fstatfs and fstatfs if STATFS_IS_STATFS64 is non-zero.
	* sysdeps/unix/sysv/linux/generic/wordsize-32/statfs.c: Ditto
	for __statfs and statfs.
	* sysdeps/unix/sysv/linux/alpha/kernel_stat.h: Set STATFS_IS_STATFS64
	to 0.
	* sysdeps/unix/sysv/linux/generic/kernel_stat.h: Ditto.
