Boost.Build request for error checks

Boost.Build would be a little easier for users if the following errors were 
detected and reported:

*  BOOST_ROOT not defined.

*  BOOST_BUILD_INSTALATION not defined.

*  A later version of the Jam executable is required by Boost.Build.

*  The compiler specified isn't configured correctly; variables required by 
that compiler aren't defined.

*  The compiler specified isn't configured correctly; for unknown reasons, 
the compiler can't compile and execute even a simple "hello, world, using 
<iostream>" program which doesn't even use any of the Boost libraries.

*  A simple "hello, world, using <iostream>" program (which doesn't use the 
Boost libraries) compiles and executes OK, but for unknown reasons, the 
compiler can't compile and execute even the simple 
boost-root/libs/config/config_test.cpp test program.

Note that none of the above are theoretical; in testing yesterday I made 
every errors which the above checks would have detected, except for the 
wrong version problem, and some else reported that problem.

OTOH, once I got the environment variables set right, directory and file 
names spelled right, etc, the threads library built right away.
