Here's a simple recipe to make a debug version linux-yocto. It includes 
the real recipe then overrides KERNEL_PACKAGE_NAME and PROVIDES so that 
two sets of kernel* packages can co-exist in the feed. The other file is 
a kernel config snippet which enables some extra debug options.

[linux-yocto-debug_3.19.bb]
include linux-yocto_3.19.bb
KERNEL_PACKAGE_NAME = "kernel-debug"
PROVIDES = ""
SRC_URI += "file://debug.cfg"

[files/debug.cfg]
CONFIG_DEBUG_INFO=y
CONFIG_FRAME_POINTER=y
CONFIG_LOCKUP_DETECTOR=y
CONFIG_DEBUG_PREEMPT=y
CONFIG_KGDB=y
CONFIG_KGDB_KDB=y
CONFIG_EARLY_PRINTK=y
