kernel compiling

Good afternoon.
I wonder how I can compile the kernel having possibility of debugging it.
It is well known that comfortable debug process require such compilation parameters as "-g -O0".
But the Makefile contains only "-Os" and "-O2".
Trying replace -O2 with -O0 I got an error at some stage of building:

The question is, how to compile the kernel keeping in mind further possibility of debugging?
