KASAN uses a single cc-option invocation to disable both conserve-stack and stack-protector flags. The former flag is not present in Clang, which causes cc-option to fail, and results in stack-protector being enabled. Fix by using separate cc-option calls for each flag. Also collect all flags in a variable to avoid calling cc-option multiple times for different files.
