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.

Better handle the second pass core gcc build, differentiating between gcc prior to 4.3 with gcc from 4.3.
Simplify detecting wether gcc is 4.3 and later, or older than 4.3 (we already know from .config).

Don't check for autoconf >= 2.50.
It was needed by glibc and eglibc to re-generate their 'configure' files, but they no longer do (in fact never did).

Had a new known issue: ccache will break the build because we're sym-linking to have our own compiler for host and build systems, but that screws up ccache finding the real compiler.
There is no fix, so the only way to inform the users is to document it: remove ccache.
