Adhemerval Zanella e0d2eb5a79 linux: Implement tmpfile with O_TMPFILE (BZ#21530) 
This patch adds O_TMPFILE support to tmpfile on Linux.  This is
similar to the previous suggestion by Andreas Schwab [1] with the
difference the file descriptor creation is parameterized to
compartmentalize Linux only open flags (O_TMPFILE) on sysdeps.

Checked on x86_64-linux-gnu.

	Adhemerval Zanella  <adhemerval.zanella@linaro.org>
	Andreas Schwab  <schwab@suse.de>

	[BZ #21530]
	* include/stdio.h (__gen_tempfd): New function.
	* stdio-common/Makefile (routines): Add gentempfd.
	* stdio-common/gentempfd.c: New file.
	* sysdeps/unix/sysv/linux/gentempfd.c: Likewise.
	* stdio-common/tmpfile.c (tmpfile): First try to use a system specific
	unnamed file first.
