Hi, I just face this problem with kernel 4.4 and VirtualBox 5.0.12 also:

Confirmed that 4.5 guest additions build with just released 5.0.14. Thanks.

Thanks for the feedback!

Guest additions broken with 4.6 kernel (though the make.log file is much smaller and this appears to be a different type of error than usual). Filed https://www.virtualbox.org/ticket/15270 .
