Build System Default Kernel
Update the method used for determining which kernel to build against when not specified. Previous 'uname -r' was used but this makes the assumption that the running kernel is the one you want to use, this is often not the case. It is better to examine the usual kernel-devel install locations and select one of the installed kernels.
