Do not do that. Bad things will happen, the kernel really does not like
this at all.
Why do you want to build the kernel with "O0"? What problem are you
trying to solve that you think this will resolve it?
Also, 5.4.21 is very old and obsolete and known insecure. Please use a
more modern kernel version.
