Like I explained in my first email, using PROFILE can append extra options to CFLAGS, I am always use this method to
append‘-O0’ to CFLAGS. However, this way is easy to missing the extra option to add. As CommitFest CI always enable
-Wshadows,we should allow developers to always enable the option in local.
