Revision: 2637
Log message:
Added ENSROOT and OCAMLSRC to mk/config.
When the mk/config is created for the first time, the environment
variables would be consulted and if they point to existing directories,
they would be added to mk/config, otherwise "undefined" is used.
Once ENSROOT and OCAMLSRC are entered into mk/config,
make would ignore ENSROOT and OCAMLSRC environment variables
