byacc: fix compilation on Ubuntu 14.04

Ubuntu defaults to passing _FORTIFY_SOURCE=2 which breaks byacc as it doesn't
pass enough arguments to open():

inlined from 'open_tmpfile' at byacc-20150711/main.c:588:5:
/usr/include/x86_64-linux-gnu/bits/fcntl2.h:50:24: error: call to '__open_missing_mode' declared with attribute error:
open with O_CREAT in second argument needs 3 arguments

Add a mode of 0666 to fix this.

(From OE-Core rev: f906c5eb722de07eb09858fd058eb7e20103df71)
