Obsolete nfsservctl.

Browse Source 
The Linux nfsservctl syscall was removed in Linux 3.1.  Since the
minimum kernel version for use with glibc is 3.2, the glibc wrapper
for this syscall can no longer usefully be called.  This patch makes
it into a compat symbol, not provided at all for static linking or new
ports.  (It was already the case that there was no header declaration
of this function.)

Tested for x86_64.

	* sysdeps/unix/sysv/linux/syscalls.list (nfsservctl): Make into a
	compat symbol, disabled for minimum symbol version GLIBC_2.28 and
	later.

binaries; the headers <ustat.h> and <sys/ustat.h> have been removed. This
function has been deprecated in favor of fstatfs and statfs.
* The obsolete function nfsservctl is no longer available to newly linked
binaries. This function was specific to systems using the Linux kernel
and could not usefully be used with the GNU C Library on systems with
version 3.1 or later of the Linux kernel.
