I have just installed the latest arm image for Pi3 and after a few compliling issues I realised there is a mismatch between the kernel version provided by uname and the installed mage and associated files.
apt and everything else seems to agree that it is running 4.9.0 while uname shows 4.4.50. Due to this compils fail as they use uname to determine the version to compile against
