I have the below in my Makefile:

# Strip -fomit-frame-pointer and add -g when compiling with GDB support
ifeq ($(CONFIG_DEBUG_KERNEL_WITH_GDB_STUB),y)
CFLAGS := $(CPPFLAGS) -Wall -Wstrict-prototypes -O1 -g
endif


If built with -fomit-frame-pointer GDB crashes in a second when it
tries to unwind the stack for its own clueless purposes.
