Only blacklist the TSAN file when using clang compiler #1713

This solves #1656

When enabling TSAN on my system using gcc my build fails because -fsanitize-blacklist is not supported. I'm not sure if gcc currently supports this at all, at least the latest version (8.2.1) on the Fedora 29 repository doesn't. I tried using check_cxx_compiler_flag to check if -fsanitize-blacklist but this didn't work on MAC, so I'm now just checking for the only supported compiler (Clang).

In my searching I have found: which allows a file to be specified with special key:value pair options using the environment variable: TSAN_OPTIONS=suppressions:filename .This may be useful in future

Tested on a system which supports (Mac/Clang) and doesn't (Linux/gcc).

Unrelated: exception specifiers are deprecated in c++11 so display a warning, this is removed.
