Build System Default Kernel

Browse Source 
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.
