Subject: [boost] Strict or lax build configuration

I have a question how building Boost should behave when the user
provides wrong configuration information. E.g., suppose you have this in
using python : 3.20 : /nowhere ;
or alternatively, in 1.42 a user runs Boost.Build as follows:
./bjam -sZLIB_INCLUDES=/still-nowhere ...
What should happen?
- A hard error. After all, the user wanted that specific configuration. And
warnings are easy to miss.
- A warning. Autodetection will still run and possibly find a random version
- A hard error, but also run autodetection and let user know what was found.
Could not find Python version 3.20 in /nowhere.
There is a valid installation of 2.5 in /usr.
Remove the 'using python' statement to use it.
