Using clang with fsanitize results in an incompatible ASan runtime. It results in the warning message "linked against incompatible ASan runtimes". This only occurs with the mixed Fortran/C demo. * tests/f77demo.at: Skip tests for clang compiling with fsanitize. * tests/fcdemo.at: Skip tests for clang compiling with fsanitize.
