This does technically work, but this feels like the wrong solution. Also, this won't work for another case where I need a similar thing: if the .scl file for the integer sanitizer changes, we need to do the same full rebuild, and that's not a C file. I think we need to explicitly inject something into fixdep... -- Kees Cook
