Error when compiling in Ubuntu 16.04 - /usr/include/x86_64-linux-gnu/bits/fcntl2.h:50:4: error: call to '__open_missing_mode' declared with attribute error: open with O_CREAT or O_TMPFILE in second argument needs 3 arguments

Hi Tavis,

I tried compiling in Ubuntu 16.04, but can't really figure out how to fix it at the moment.
This is the error I get:
Checking for glib-2.0...ok

Thank you.

Update:

I kinda did a workaround by adding permissions.
From util.c:
154 gint fd = open("/tmp", O_TMPFILE | O_RDWR);
To:
154 gint fd = open("/tmp", O_TMPFILE | O_RDWR, 0755);

Thank you for the bug report! I don't know why I don't get that error when compiling, but I think you're right that's a real bug, I'll fix it right now.
