Save the toolchain configuration to its own file, as an auto-extracting shell script:
- get rid of the 'extractconfig' action, it was cumbersome to use, and badly documented,
- introduce a skeleton for the config script,
- update auto-completion,
- document the config script.

       It is highly recommended that 'make check' is run against the newly built

       MPFR library. See http://gmplib.org/
