This change stores a Kernel with Debug-Symbols for the current architecture in a new output directory '<outputdir>/debug'. This allows a developer or operator of a network to store the kernel along with the actual images. In case of a kernel oops the debug information can be used with the script 'scripts/decode_stacktrace.sh' in the kernel source tree to get the names to the symbols of the stack trace. OpenWRT already provides the CONFIG_COLLECT_KERNEL_DEBUG -option that creates a kernel with debug-symbols in the OpenWRT output directory. This change enables this option and copies the generated kernel to the gluon output directory. Signed-off-by: Chrissi^ <chris@tinyhost.de>
