  Log Message:
  -----------
  [Clang][Driver] More explicit message when failing to find sanitizer resource file

Compiler-rt doesn't provide support file for cfi on s390x ad ppc64le (at least).
When trying to use the flag, we get a file error.

This is an attempt at making the error more explicit.
