  This patch adds the AT_RECURSIVE constant from Linux 5.2 to glibc's
fcntl.h.  (Existing practice in glibc is that the AT_* constants go
directly in io/fcntl.h rather than somewhere OS-specific.)

Tested for x86_64.

	* io/fcntl.h [__USE_GNU] (AT_RECURSIVE): New macro.

Patch looks good to me.  The definition matches the Linux sources.
