glibc 2.27 fix
With glibc 2.27 the memfd_create has been added to the devel libraries. That's causing the internally defined static function to clash with the system wide one. This patch addresses that issue on systems with latest glibc libraries. Change-Id: I788bf49b23d5b5f1cb1c0374e243d8a429178a71 Signed-off-by: Marco Varlese <marco.varlese@suse.com>
