Alexandru Croitor dc4bc1e575 CMake: Fix interleaved configure output 
message(STATUS) prints output to a buffered stdout, whereas
message(NOTICE) or just message() print to unbuffered stderr.

We use a mix of message() calls when printing the configuration
summary, which caused interleaved output.

Because CMake offers no message(FLUSH), we work around the issue
by calling execute_process(COMMAND -E echo " ") which does
call std::cout << s << std::flush;

We seem to have to do it twice, before and after the
detailed configuration summary is printed.

Pick-to: 6.2 6.3
