Latest Git kernel doesn't compile because of the LINUX_VERSION_CODE issue

[Christian Zigotzky]

Hello Christophe,

Thanks a lot for compiling the latest git kernel.

I have solved the compiling issue through setting up a value for the 
SUBLEVEL variable in "a/Makefile". Before it wasn't necessary to set up 
a value for the SUBLEVEL variable.

Cheers,
Christian
