In that case you should get something like this, during kernel build: scripts/Makefile.kasan:17: Cannot use CONFIG_KASAN: -fsanitize=kernel-address is not supported by compiler
Also you may check you gcc by compiling simple program: $ cat test.c void main(void) { }
$ gcc -fsanitize=kernel-address test.c
