Restore development version (revert previous commit)

Revert the previous patch now that the binary for the super-final
of TCEC season 16 has been sent.

Maybe the feature of showing the name of compiler will be added to the
master branch in the future. But we may use a cleaner way to code it, see
some ideas using the Makefile approach at the end of pull request #2327 :
