[Bug sanitizer/61978] implement blacklist for sanitizer


https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61978

--- Comment #7 from Daniel Pinol <gcc at dpinol dot com> ---
thank you everybody for your great feedback!

@kostya: I provide here the full log. Even removing the #if's, it still aborts.
strict_memcmp=0 worked like a charm. Thanks!

I guess there's no way to just report the errors but not abort execution,
right?

  '*.LC2' is ascii string ''
